Chitosan Nanoparticles

Chitosan (CS) the second most abundant biopolymer in nature next to cellulose, derived from the exoskeleton of shrimps and other crustaceans is one of the very few positively charged natural biopolymers existing in the world. Due to its unique characteristics of biodegradability, biocompatibility, bio-adhesion, and non-toxicity, CS nanoparticles (NPs) are used as drug delivery systems, nanofibers, biosensors, and edible films. Micro and nanoparticles of chitosan can be produced in different ways, although deprotonation and ionic crosslinking are advantageous techniques considering the low complexity and the needless of high shear forces application or addition of harsh organic solvents.
