Nonmetallic nanoparticles and nanomaterials: Size-dependent behavior of mechanical properties is still not clear in the case of polymer nanomaterials however, in one research by Lahouij they found that the compressive moduli of polystyrene nanoparticles were found to be less than that of the bulk counterparts.
Nanomedicine is the medical application of nanotechnology. [1] Nanomedicine ranges from the medical applications of nanomaterials and biological devices, to nanoelectronic biosensors, and even possible future applications of molecular nanotechnology such as biological machines.

Nanoparticles can generally carry drugs in two ways: drugs can either be bound to the outside of the nanoparticles or packed within the polymeric matrix of the nanoparticles. [14] Smaller nanoparticles have higher surface area ratios and can thus bind a high quantity of drug, while larger nanoparticles can encapsulate more of the drug within ...
Inorganic nanoparticles have been largely adopted to biological and medical applications ranging from imaging and diagnoses to drug delivery. [22] Inorganic nanoparticles are usually composed of inert metals such as gold and titanium that form nanospheres, however, iron oxide nanoparticles have also become an option.
Polymeric nanoparticles may also contain beneficial controlled release mechanisms. Polymer Branch. Nanoparticles made from natural polymers that are biodegradable have the abilities to target specific organs and tissues in the body, to carry DNA for gene therapy, and to deliver larger molecules such as proteins, peptides, and even genes.

Protein nanotechnology is a field of research that integrates the diverse physicochemical properties of proteins with nanoscale technology. This field assimilated into pharmaceutical research to give rise to a new classification of nanoparticles termed protein (or protein-based) nanoparticles (PNPs).
[1] [2] [3] These complex networks of polymers present a unique opportunity in the field of drug delivery at the intersection of nanoparticles and hydrogel synthesis. [ 1 ] [ 2 ] [ 3 ] Nanogels can be natural, synthetic, or a combination of the two and have a high degree of tunability in terms of their size, shape, surface functionalization ...
