Pharmacotechnical development of biopolymer nanostructures of chitosan to release bioactives

Abstract

Nanostructured drug delivery systems are formulations containing particles usually fabricated with polymers. They can be administered by all drug routes (depending on their characteristics) and in various pharmaceutical forms, including nanoemulsions, nanosuspensions, nanofilms and lyophilized powders. The size, shape and surface load influence the functionality of nanoparticles, as well as their stability.
