| Abstract | Chitosan, a useful biopolymer, was obtained from pulverized shells of blue crabs via demineralization, deproteinationand de-acetylation. The chitosan was converted to nanoparticles using sodium tripolyphosphate (TPP). The FTIR spectrum ofchitosan nanoparticles showed various functional groups, such as hydroxyl, carbonyl, and amine among others, as expected inchitosan. The SEM analysis revealed clusters of crystals at the surfaces, while TEM showed a very smooth and fine surfacemorphology. The particle size was estimated at < 200nm. The XRD spectrum showed shifting of the 2? peaks angles 10 and 20ofor normal chitosan to 17 and 25ofor the chitosan nanoparticles. The TGA and its derivative (DTGA) showed that the biopolymerwas thermally stable. |
