According to the growth of using Nano products, concerns regarding the quality and safety of them are increased. How to identify the best Nano products is the main question. Nanotechnology has provided the best methods and approaches for the synthesis and use of nanoparticles in various industries, especially in products related to food and healthcare. Advances in nanotechnology will make it possible to solve such medical issues as the restoration of damaged organs, the diagnosis and treatment of cancer, the production of appropriate microsystems for the delivery of effective drugs, the creation of artificial tissues, and so on. Today, however, concerns about the safety, environmental, and regulatory issues of nanotechnology products have increased due to the possible toxic and hazardous effects of nanomaterials. The main safety problem is the lack of public awareness of the impacts of nanoscale materials on human health and the environment. The complexity of describing various nanomaterials used in foods, their detection and measurement in food and biological systems, the lack of optimal experimental methods, and the limited information on toxicology and toxicity make it difficult to assess risks and manage nanotechnologies. Approaches to carefully assess and control the quality of nanotechnology products include regulatory compliance and consumer health and safety. 
The fear is based on the hypothesis that there will be danger and damage to humans and the environment when shrinking and converting various materials into very small particles in Nano scales, however, almost all specialists and practitioners in this field believe that such fears are undoubtedly normal for nanotechnology as new technology. The existence of such concerns about most artificial technologies has never stopped the production of science, technology, and industry. Rather, governmental and non-governmental institutions have sought to create a framework and regulations to control, manage, and prevention of the negative effects of these technologies. To identify the best and safe Nano products we must learn certain points to help us choose better. Knowing the safety techniques to reduce the hazards associated with nanomaterials during operation, as well as safe methods for their use and production is a necessity. Even if you are not aware of detecting these hazards in products, you must purchase Nano products from reputable factories with clear formulations.
Best Nano products
Nano products have been changing and developing our lives and numerous industries in the best way. Nano products are the outcome of either using nanotechnology or nanoparticles during the production of the goods. Nanoparticles have unique properties giving unique features to the products. In the nanometer world, everything is different from what is known in the human world, the interactions between atoms do not obey classical physics, so to interpret their behavior, it is necessary to use the laws of quantum mechanics. Nano products and nanotechnology accelerated the process of dealing with problems we are facing in medication, agriculture, construction, and other industries. 
The use of nanotechnology in agriculture has made it possible to produce more crops with fewer raw materials. Nanomedicine is also an emerging field that uses the tools that nanotechnology provides to medical engineers and physicians to create devices such as Nano biological robots and nanochips. Nanomaterials have also revolutionized optics. Common applications for these devices are lasers and LEDs. The optimal performance of these devices is directly dependent on factors such as the precise size of the component's thin-film diameter and the controlled properties of the surface. Advances in nanotechnology will allow us in the future to see very thin, durable, and fully transparent 3D folding screens that do not need to control the light, and by adjusting the angle of the nanocrystals, the image will be visible only to the owner. In the sports industry, baseball gloves are made of carbon nanotubes, making the gloves lighter and more functional. More uses of nanomaterials in this industry could be identified using antibacterial nanotechnology, such as towels used by athletes to prevent bacterial diseases. Using nanotechnology to deliver drugs to the body can reduce the side effects of drugs and make drug delivery smart and targeted. 
Researchers could use intelligent nanoparticles to cross the blood-brain barrier to penetrate brain cancer cells and design a drug delivery system that can be treated with two modalities: two chemotherapy (administrating chemotherapy to these cells) and radiation therapy (radio absorption) to increase cell temperature and kill cancer cells. The use of nanomaterials in the energy sector is beneficial in that it can make existing methods of energy production, such as solar panels, more efficient and cost-effective, as well as create new ways to use and store energy. When we can consider the Nano products the best ones in the case, they are beneficial with no side effects and hazards.
Nano products quality
Nanomaterials included in Nano products are the reason for the high quality and better function. The properties of nanomaterials, particularly their size, highlight their usefulness in terms of flexibility to adapt to specific needs, as well as offer numerous advantages over other materials. One of the reasons the world is paying attention to this is that Nano has somehow generated wealth and we can see an improvement in the quality of life. A further advantage is a high porosity, which again increases the demand for use in industries. Nanotechnology can be used in the food industry to produce, process, store, and control food quality. Nanomaterials, unlike conventional microscale materials, due to their new properties, can provide new textures, colors, and appearances to improve food quality. 
The characteristics of Nano products include product durability, quality improvement, and cost reduction, so let's take a look at all aspects. There is at least one economic benefit to applying nanotechnology to products. For example, when a nanocoating is applied to a part, it can increase the durability and working life of the part by a factor of 10. In other words, it gives the part scratch-resistant, wear-resistant, and heat transfer properties. Nanotechnology is used to design Nano sensors and identify hazardous ingredients in food and intelligent packaging systems. This is because food contamination can be detected very quickly and with sensitivity. Smart and healthy packaging has brought innovations in the future of food and other industries. New packaging is being improved using nanotechnology to improve food shelf life by improving its mechanical, antibacterial, and inhibitory properties. Nanotechnology has played an important role in the field of agriculture as well by changing and influencing the formulation of fertilizers and producing materials with suitable and unique properties, and the use of this technology in fertilizer production has increased the quantity and quality of agricultural products and reduced the process of environmental degradation. 
The production of fertilizers containing nutrients consumed on the nanometer scale increases the dispersion of these nutrients in the soil and improves the efficiency of absorption of these elements by plants. The use of Nano-fertilizers also reduces the loss of nutrients due to water consumption. The performance and efficiency of nanotechnology products are important to buyers. Evaluation units in factories using nanotechnology must be able to perform quality control tests, including tests to evaluate the scale and characteristics of products.
Are nano products safe
Human society's awareness of Nano products and nanomaterials being safe in the workplace, laboratory, home, and environment are now more than ever before, but to date, no specific human disease or enormously harmful environmental events induced by these materials have been identified or reported. Knowledge and awareness of the risks of nanomaterials have gradually changed, moving from the general concept of dangerous microhazard to the fact that the safety of nanomaterials must be based on specific consumption, application, type, and severity of exposure and specific characteristics of each nanomaterial. While universities and industry are always facing the realities of the dangers of nanotechnology (and all other fields and emerging phenomena) and realistically looking at them, the media and the public have great potential to move away from realism and escalate the problem they react irrationally to such unproven risks. People's opinions today are often based on unsubstantiated reports from the media and non-governmental organizations. 
As long as the information is not clear and there are no proven results on Nano safety, the pessimism that this will materially hinder the development of the market and nanotechnology will continue. Instead of disclosing some information about nanotechnology-based products, manufacturers and suppliers are intentionally keeping it secret, which in the long run can undermine people's credibility and the mental image of nanotechnology. One solution can be Labeling or including the formulations of products. What has been done so far in the fields of health and safety and the nanotechnology environment is far less than necessary. Considering the United States as a pioneer and model for this field, the first actions and activities in the field of Nano safety in this country were carried out in 2000 by organizing several workshops. However, since the end of 2008, the speed of research and regulatory monitoring in the field of Nano safety has accelerated, resulting in a significant increase in the number of papers published in the field of Nano safety. We can consider the Nano products to be safe in case the limitations and regulations regarding the process of creation and packaging are applied and if they are approved in the quality control section.
Nano alternatives
Application nano products and nanomaterials as the perfect and more efficient alternatives in many industries, has been growing more than ever. Nanomaterials are a group of materials that have found various applications in today's modern world. However, the growth of nanomaterials is very high and there is still a lot of room for improvement in such a way that Nano products will replace conventional products. In almost all cases, the use of nanomaterials improves the properties and creates new features in the final product. Therefore, the applications of nanomaterials in various industries are very. Having significant features and high quality, nanomaterials and Nano products would be the perfect alternative for products that take more energy, effort, cost, and manpower to be made. 
One of the applications of nanomaterials that all humans have become involved with is the use of sunscreens. The problem with old sunscreens and creams that do not use nanomaterials is that they have a very short shelf life. However, sunscreens based on titanium Nano oxide offer several benefits to consumers. Zinc and titanium nanoparticles are UV resistant just like solids, and when used in sunscreens, the skin's durability and radiance are increased. The luminosity of this compound has led to the application of nanomaterials in other cosmetics. Another alternative application is in glasses. The first glasses to use anti-reflective properties for the sun were glasses made of nanomaterials. In fact, one of the applications of nanomaterials is as a coating on glass surfaces. Other important applications for the use of nanomaterials in eyeglasses include scratch resistance, self-cleaning, and gloss properties. We may include nanotechnology as a suitable and beneficial alternative in so many industries.
Nano products online
How to buy Nano products online might be a challenge for people interested in Nano products. Having so many applications and benefits Nano products are popular worldwide. Analysts believe that nanotechnology, biotechnology, and information technology (IT) are the three scientific areas that make up the Third Industrial Revolution. As you can not see or touch the products to be sure about the quality, you must pick the right and reputable company to buy the Nano products or nanomaterials from. 
In case you want to initiate a cooperation with a Nano production or distributer company for trading, providing raw materials for your own company, resell in domestic production, you can go and visit the company and the production line. For small purchases, the only option you have is to risk it and order one product to make sure the quality is acceptable, however for a bigger purchase you may ask for a sample or a trial order first.
Toxicity of using Nano products
Toxicity in using Nano products of different types has become a concern to people. Nanotechnology is the ability to manufacture, control, and use materials on the nanometer scale. Particle size is very important in nanotechnology. This is because, at the nanoscale, the dimensions of material greatly affect its properties, and the physical, chemical and biological properties of individual atoms and molecules are different from the mass properties of the material and this size varies by material. Being this small makes the nanoparticles quite powerful in physical and chemical reactions and sometimes unpredictable in case of new experiments. Men are always afraid of the unknown, so since our knowledge is not completed regarding nanotechnology, these concerns still stay among people. Nanometer dimensions improve the physical and chemical properties of materials, increasing the interaction of nanomaterials with living tissues. Nanoparticles pass through biological membranes and enter cells, tissues, skin, respiratory tract, and digestive organs. It destroys organ structures inside the cell and eventually causes cell death. Animal studies have shown lung effects from inhalation of nanomaterials, such as inflammation, fibrosis, and carcinogenicity of some nanoparticles. Skin contact with nanomaterials and exposure to swallowing are also of concern. However, using the Nano products itself have no harm or biohazard to the body since all the Nano-related products will be checked and approved to be safe for human and nature. Exposure to nanomaterials occurs in three modes. Occupational exposure includes people dealing with nanomaterials in factories and laboratories. The second is consumer exposure for those who overuse products manufactured with nanotechnologies, such as cosmetics, health, and pharmaceuticals. 
Finally, environmental aspects related to water, air, and soil micro-pollutants. To avoid the risk of exposure to nanoparticles, it is important to know that there are three main ways by which nanoparticles enter the human body. Breathing, skin contact, gastrointestinal swallowing. In recent years, significant advances have been made in the methods of nanomaterial hazard assessment. These advances are based on systems biology approaches, and new and emerging tools used to assess and manage the risk of nanomaterials to humans and the environment over the life cycle of these materials. As long as you are using qualified and standard Nano products, you do not need to worry about any toxicity.
Is there any toxicity of using Nano products
Nanomaterials have unique properties that affect their toxicity because of quantum size and large surface area on volume. Recent research shows that materials that are harmless in the mass state increase their reactivity at the nanoscale and can have toxic, hazardous, and detrimental effects. The use of engineered nanomaterials (ENMs) today has many advantages in many areas of human life, and of course, the safety assessment of these materials is a very special priority. However, identifying the properties of nanomaterials that cause toxicity is challenging because of the wide variety of properties of these materials. Silver nanoparticles are one of the valuable products of nanotechnology that today finds many applications in various sciences, especially in biology and medicine. They have antibacterial, antifungal, antiviral, and antibacterial properties. Additions of these nanoparticles to coatings can create an antibacterial surface and remove contaminants. As the application of silver nanoparticles increases, so does the potential for human exposure to these substances. To date, the toxic effects of some nanomaterials have been demonstrated to some extent, which has limited their use to some extent. 
Nanoparticles may enter the body from different pathways silver nanoparticles have been reported to enter the bloodstream when taken orally, respiratory, or subcutaneously and accumulate in some organs of the body, causing liver or kidney, or blood cell poisoning. The toxicity of nanosilver is due to the production of oxygen-free species. These substances are short-lived chemical mediators that are derived from oxygen in the metabolic pathways of all aerobic cells. Silver nanoparticles, like other biomaterials, are able to produce toxic effects on living organisms. The toxicity created by these particles depends on their properties and type. Silver nanoparticles are produced by physical, chemical, and biological methods and their toxicity varies according to factors such as type of application, characteristics of particles such as shape, size, concentration and chemical composition, and living system involved (plant, animal, human, microorganism). So far, limited studies have been performed on the effect of silver nanoparticles on the health of the body, and many dimensions of the interaction of nanoparticles with different organs of the body, such as the heart, remain unknown. Since silver nanoparticles account for 56% of the world's nanoparticles, the safety aspects of nanomaterials must be considered. Numerous products are made using silver nanoparticles, however, the amount included in the products is standard in which there would be no harm or dangers to the body or the organs.
Nano products in energy
Energy plays an important role in human lives and Nano products have evolved and developed in this field alongside others. Nanotechnology is the understanding and application of new properties of materials and systems in this dimension to reveal new physical effects. It is mainly influenced by the dominance of quantum properties over classical properties. Nanotechnology is a highly interdisciplinary science and has implications for fields such as materials engineering, medicine, pharmacy, drug design, veterinary medicine, biology, applied physics, semiconductor devices, supramolecular chemistry, and even mechanical engineering, and electrical engineering, and chemical engineering. This incredible technology could make a major difference in so many industries. Regarding energy, Nano products are the reason we would be able to save natural energy. The high-adhesive insulating coating technology on metal surfaces is one of the new technologies to prevent energy and heat loss using nanotechnology. This type of paint is suitable for places where energy and maintenance costs are important and also in cold storage, motorhomes, poultry farms, farms, material tankers, and especially in cases where due to the large thickness, corrosion of metal surfaces, and weak traditional insulations. 
This insulating paint replaces conventional foam insulation, which is pollution-free and environmentally friendly. This Nano-based product is produced as airleg nanoparticles based on water-based polymer, and by using these nanoparticles, the heat transfer coefficient was reduced, and the efficiency and effectiveness of the product increased by 86% compared to non-Nano samples. The very low heat transfer coefficient at low thickness is another important feature of this product, and traditional thick foam insulation is effective and poses problems in the workplace. Energy insulating paints have unique properties, Non-penetration, Increased resistance to heat transfer Increased resistance to wear and corrosion Self-cleaning properties of surfaces. Whereas conventional insulation materials are contaminated and toxic, this product is non-toxic and repairable, can be applied to a variety of shaped surfaces, mold and bacteria cannot grow, UV and weather resistance, high resilience, low durability, high resistance closed cellulosic Moisture absorption and moisture penetration due to structural temperature changes and shock and shrinkage and expansion, susceptibility to casting and absence of respiratory problems and fire hazard are some of the features of this product. 
By using this technology, we can reduce the cost of catalysts used in fuel cells. These catalysts produce hydrogen ions from fuels such as methanol. Nanotechnology is also used to improve the performance of membranes used in fuel cells to separate hydrogen ions from other gases, such as oxygen. Companies working in the field of energy are using nanotechnology to make more efficient and high-quality membranes. building lighter-weight and longer-lasting fuel cells is the result of this application. Professional and experienced staff is required for Supplying Nano products and nanoparticles and exporting them throughout the world.
