Abstract

Chitosan is an amino polysaccharide 2^nd abundant biopolymer after cellulose is most R & D explored in diversified fields like biology/biochemistry, organic/polymer chemistry, pharmacology and medicines as being remarkably reported numerous publications/patents. Chitin/chitosan matrix is facile to physico-chemical modifications, in highly sophisticated functions resulting new biocomposites owing greater possibilities widespread over cellulose. Purity/quality condition of this chitosan offered as high, mid and industrial grade that’s facile for formulation and to provide solutions of problems in varied fields due to unique parameters viz; bio-compatibility, non-toxicity, anti-microbials and hemeostatic agents. This mini review describes the suitable formulated/fabricated/altered products like biomarkers, biosensors, quantum dots etc, with adoptable higher productive utility of chitin/chitosan chemistry in nano-science and technology.
