“…Polymeric nanoparticles -efficient for targeted drug distribution -possibility to modify shape, composition, size, and surface characteristics -stability -high therapeutic efficiency -large encapsulation capacity -toxic degradation -difficult encapsulation for hydrophilic drugs [33][34][35][36][37] Carbon nanotubes -cylindrical shape with a closed end, suitable for antimicrobial agents and gene delivery -electrical conductivity -resistance -high specific surface area -insoluble in aqueous and organic solvents [14,33,36,38] Liposomes -externally formed from a double hydrophobic phospholipid bilayer that can be modified to reduce side effects, while the interior is represented by an aqueous core in which drugs, proteins, genes, or peptides can be encapsulated -specific drug transport without degradation -high biocompatibility -high permeability of drug distribution -sensitivity to extrinsic and intrinsic stimuli [14,33,36,[39][40][41][42] Gold nanoparticles -exhibit unique optical properties and have the ability to conjugate with antibodies -water solubility -extremely stable -low toxicity -biological stability may decrease in vivo [33,36,[43][44][45] Figure 1. Advantages of nano systems in medicine [18,[29][30][31].…”
