Abstract The exoskeleton of marine shrimp contains a natural, biocompatible polymer chitin, which is
dumped as a waste. The study proposes the sustainable single-pot-extraction of chitosan from
the waste and its use in the fabrication of wound-dressings, and thus leverage its piezoelectric,
antioxidant, hypoglycaemic and medicinal properties in wound-healing. The Fourier transform
infrared spectrum revealed that marine chitosan contains functional groups with N-O, O-H, and
CO stretching. Scanning electron micrographs demonstrated the spherical and mesoporous
structures of the extracted chitosan. X-ray diffraction analysis showed a semi-crystalline phase
of chitosan particles with a mean size of 28.9 nm. The film prepared with… More >
