Utilization benefits in the fields of electronics and computing
The discipline of electronics is going to be completely transformed by nanotechnology
For instance, quantum dots, for instance, are not truly dots at all but rather very small cells that generate light and may be used for a variety of applications, including lighting as well as the displays of mobile devices, televisions, and more
Silicon chips may also have millions of components, but the technology aims to obtain the fewest feasible components at the same time
Circuits may be made so tiny with the use of nanotechnology in some areas that if even a single molecule is out of place, the circuit will no longer operate as it should
In fact, nanotechnology makes it possible to build circuits with a very high level of accuracy at the atomic level
The field of medicine stands to benefit significantly from the use of nanotechnology
For the purpose of removing obstructions, for instance, nanorobots might be inserted into a patient's veins with the assistance of nanotechnology
On the other hand, surgery can become more rapid and accurate, damage can be corrected cell-by-cell, and even people's genetics may be improved by deleting defective genes from their genomes
Nanotechnology could also be used in the pharmaceutical industry to make it easier to make medicines and lessen the side effects of those medicines at the same time
Some scientists in the field of nanotechnology have voiced bizarre and pessimistic predictions concerning future issues
For instance, the term "grey goo" is associated with a terrifying future scenario in which nanobots would eat everything in their environment and reproduce by multiplying themselves
Eric Drexler, an American engineer, is credited as being the first person to ever use the word in his book (1986)
This notion, which has also been referred to as the "nanotechnology nightmare," was formerly extensively debated, but it is no longer seen as a credible danger
Even so, there is a chance that nanotechnology will hurt the environment because it has the potential to make new poisons and pollutantseconomic development
There is a good chance that nanotechnology, just like previous innovations that came before it, will bring about significant shifts in a variety of aspects of the economy and finance
Although items manufactured using nanotechnology will initially be unique, luxury, or very costly specialty items, as they become more ubiquitous, a wider range of markets will experience the economic effect of these products
On the other hand, it is possible that some technologies and materials could become outdated, which would result in the closure of businesses that specialize in these areas
Consequently, as a result of the changes in industrial processes brought about by nanotechnology, there may be a loss of jobs

nanotechnology in medicine essay
People who have had a heart attack, for example, have a weak heart that sometimes fails, but the illness is not severe enough to require surgery
The best option for this is to employ nanomedicine
An MIT team of engineers, surgeons, and materials scientists used nanotechnology to repair the heart, among other things
By collaborating with tissue engineers and using gold nanowires, they were able to repair damaged portions of the heart as well as non-functioning and dead tissue
Magnesium nanoparticles that can get into damaged tissue and help heal it are also used
Despite the importance of this task, we must acknowledge that it is difficult to do
Heart cells are difficult to make in the laboratory, and employing nanomaterials to regenerate heart cells and synchronize cells with one another to prevent cells from being rejected by the body is an urgent problem
Even when the cell-making phase is complete, the new cells must work in the same direction as the old ones, and the tissue's activities must be in sync
The resultant fabric presented complications and did not operate effectively in early iterations of this procedure because it was not a strong conductor
Nevertheless, following attempts, they found a direct link with heart expansion and contraction by adding gold nanowires
Electrical conductivity has also been substantially improved
Nanoparticles
Another use of nanotechnology is drug-carrying nanoparticles that stick to the walls of certain arteries and gradually deliver medicine into the body over time
One of the most important things about these nanoparticles is that they can find damaged tissue, stick to it, and then slowly inject their drug payload into it
Sound pulses are nanoparticles that transport drugs throughout the body
These particles, which contain three layers and are around 60 nm in diameter, are used to carry the drug
The outer layer is coated with a PEG polymer, which protects the drug from deterioration
The middle layer is made of fat, while the drug is held in the inner core and polymer chain, which controls when the drug will be released
