Biopolymers for Therapeutic Application in Nanotechnology

Nanoparticles exist in the same size domain as proteins are this is the main reason for using nanoparticles in therapeutic applications. Their large surface areas can also allow for displaying a large number of surface functional groups such as ligands. 

Furthermore, they have a rapid absorption and release behavior provided by high abilities of their diffusion and volume change. In addition, the particle sizes and surface characteristics of nanoparticles can be controlled in a proper way. 

Similar to proteins, polysaccharides are also digested by the specific enzyme. As far as prolonging circulation time, polysaccharides have significance over synthetic polymers, such as poly(ethylene glycol].
