Utilization of blue crab shells for the synthesis of chitosan nanoparticles and their characterization [PDF]

open access: yesSongklanakarin Journal of Science and Technology (SJST), 2018
Chitosan, a useful biopolymer, was obtained from pulverized shells of blue crabs via demineralization, deproteination and de-acetylation. The chitosan was converted to nanoparticles using sodium tripolyphosphate (TPP).
