Nanotechnology is an ever growing field of science and technology for synthesizing novel material at the nanoscale level. Chitosan is very comfort for preparation of nano and micro particles for controlled drug release. Read more
Chitosan nanoparticles has many advantages due to its biodegradability, biocompatibility, better stability, low toxicity, simple nature and mild preparation methods provides chitosan as a drug delivery carrier for versatile routes of administration. Chitosan have potential to improve the stability of drugs, proteins or genes when it is formulated as chitosan nanocarriers. Chitosan nanocarriers provide suitable way for tissue engineering application as well as a good adjuvant for vaccine delivery.
They have the property to chelate metal ions such as palladium, copper, silver, iodine catalyst which can be used in health products, and insecticides. Chitosan derivatives like cyanoethyl chitosan and hydroxyl ethyl chitosan are commercially used in dialysis, insulating papers and in enzymological studies respectively. Moreover, chitosan is a linear polyamine containing a number of free amine groups that are readily available for cross linking whereas its cationic nature allows for ionic cross linking with multivalent anions.
