Penaeus monodon shell waste-derived chitosan nanoparticles show biocompatibility and broad antimicrobial activity.

ABSTRACT: Crustacean shell waste, a mostly untapped marine byproduct, presents considerable environmental risks while also offering a rich but underutilized source of biopolymers. Although chitosan nanoparticles (ChNPs) have received attention for their bioactivity and biocompatibility, most research focuses on commercial chitosan, ignoring local waste valorization, complete nanoparticle characterisation, and cross-disciplinary applications. To bridge these gaps, the current work presents an integrated, sustainable methodology to convert Penaeus monodon shell waste into bio-functional chitosan nanoparticles by green ionic gelation. Physicochemical investigations (FESEM, TEM, FTIR, XRD, TGA, and DLS) revealed crystallinity, thermal stability, and consistent nanoscale shape of the molecule. The ChNPs
