Biowaste originating from aquaculture sector represents a potential feedstock to produce value-added substances and materials like chitin and chitosan. They are the long chain polymers of N-acetylglucosamine polymers with huge industrial and biomedical significance. Chitin has long been recognized as a useful biomaterial for drug delivery and neurological therapy. Similarly, chitosan oligosaccharide, a short chain polymer derived from chitin/chitosan, has been identified for its potential biomedical applications, including antibacterial, anti-inflammatory, and anti-Alzheimer action. Chitosan nanoparticles are also used extensively in biomedical applications. Here we have critically summarized various methods for the extraction of chitin, chitosan, and chitooligossacharides and chitosan nanoparticle preparation and their diverse biomedical applications.

“…Figure 6e shows the incorporation of microcrystalline cellulosic biopolymers, which react with the polyester resin and forms a fine interface between fibre‐matrix, thus, the load transfer is uniform. Moreover, the limited volume of cellulose dispersed in the matrix uniformly, thereby improving the load‐bearing effect (Johnson et al, 2023). However, there is a noticeable decline in mechanical properties with the 4 vol.…”

In this study, a microcrystalline cellulosic biopolymer (MCB) made from Pisum Sativum (green pea) pod waste via a modified thermo‐chemical process, and Crotalaria juncea (sunn hemp) fibre was used to create environment‐friendly polyester composites. The main objective was to synthesise the MCB from domestic waste and characterize how the addition of hemp alters the strength of the polymeric composite. The MCB was synthesized using green pea pods. The sunn hemp fibres were used in mat form in this study. The composites were made using the hand layup method and post‐cured at 110°C for 2 h. The results showed that the addition of sunn hemp fibre and MCB increased the mechanical properties. Similarly, the highest observed fatigue life count for the composite designated PSC3 (2.0 vol.% MCB) was 30862 at 30% ultimate tensile stress. Similarly, the composite PSC3 had the maximum penetration resistance with an absorbed energy of 14.2 J. Moreover, the addition of silane‐treated cellulose and fibre provided an improved storage modulus of 6.8 GPa for the PSC3 composite, confirming the improved fibre‐matrix fibre interaction and increased toughness. The scanning electron microscope images revealed improved fibre‐matrix correlation. These eco‐friendly composites with better load‐bearing capabilities could be preferred in automated door panels, defence toolboxes, and home interior decoration applications.

The primary purpose of this study was to synthesize silver nanoparticles (AgNPs) utilizing chitin extracted from shrimp shell waste by simple photo-irradiation in a single-pot biosynthesis without adding any toxic chemical substances. Glucose molecules in the chitin extract act as the reducing agent, while amino acids in chitin behave like proteins and are responsible for the production of AgNPs by acting as the particle-stabilizing agent. The synthesized chitin-AgNPs were thoroughly investigated using transmission electron microscopy (TEM), Fourier-transform infrared analysis, and ultraviolet-visible absorption spectroscopy. UV-visible spectroscopy revealed a surface plasmon resonance peak at 470 nm, confirming the formation of chitin-AgNPs. FTIR data confirmed the association between chitin and AgNPs. TEM studies showed that the synthesized chitin-AgNPs have a spherical shape with particle sizes ranging from 10 to 30 nm. The prepared chitin-AgNPs exhibited intense antibacterial activity against the Gram-positive Bacillus subtilis, Staphylococcus aureus, Gram-negative Pseudomonas aeruginosa, and Escherichia coli, as well as antifungal efficacy against Aspergillus niger. Reactive oxygen species and live and dead cell assays were performed to examine the chitin- AgNPs and the results were further found to be interesting and positive. The assays revealed that the prepared chitin- AgNPs exhibited significant antimicrobial potential against B. subtilis and A. niger, with a zone of inhibition measuring approximately 6.2 mm and 30 mm, respectively. The effects of the chitin-AgNPs were compared to those of commercial agents, such as ciprofloxacin (6.0 mm) and fluconazole (25 mm). Consequently, the chitin-AgNPs developed through a greener approach show promising potential as sustainable materials for antibacterial and antifungal activities.
