Nanotechnology is a rapidly expanding field that was founded in 1974 to develop innovative materials with dimensions ranging from 1 to 100 nm.
The term nano comes from the Latin word nanus, which means "very small in size" (1 nm equals 109 meters).
Another new development is nanotechnology, which has uses in research, agriculture, and infection therapeutic delivery testing.
Furthermore, nanomaterials have the ability to influence biological applications and research in vivo and in vitro.
They stand out due to their very high surface-to-volume ratio, increased reactivity, massive surface-to-volume, stability, bioactivity, bioavailability, regulated particle size, controlled drug release, site-specific targeting and controlled entry, and new physicochemical properties.

Nanoparticle classification: Nanoparticles are classified into several categories depending on their origin, appearance, manufacturing method, and intended use.
They are classified as organic, inorganic, or hybrid nanoparticles depending on where they come from.
Mineral-based nanomaterials are generally less costly, biocompatible, and less cytotoxic.
They have new electrical and optical properties that can be tweaked throughout the construction process.
Minerals in this group include gold, silver, iron oxide, and calcium phosphate.
Organic nanomaterials, such as proteins and peptide nanoparticles, are often used in quality delivery needs because of their low lethality, cheap production cost, high biodegradability, and biosimilarity (such as gelatin).
They can also handle a wide range of loads.
Gelatin is classified into two categories: A and B, depending on how the acids and bases are separated.
A and B have distinct isoelectric points.
Gelatin B is a versatile material due to its isoelectric point, which enables it to interact with positively charged atoms at physiological pH.
Gelatin B charges in the opposite way.
In any case, it changes its charge and gets permanently charged when it comes into contact with an endosome, enabling the charged charge to be easily expelled from the cell's interior.
The gelatin molecule must be connected to a highly positive subsite, such as protamine sulfate, in order to maintain the DNA within the atom complex.
