SQUID PENS MEDIATED SILVER NANOPARTICLES SYNTHESIS, ITS CHARACTERISATION, AND BIOLOGICAL ACTIVITIES

Abstract

This research scintillates the synthesis of silver nanoparticles from chitosan (C-AgNps) from squid pens as a reducing and stabilizing agent and assesses its antioxidant, antibacterial, and anticancer potentials. The nanoparticles were 240 to 290 nm with excellent stability of +98.2 mV. The C-AgNps possessed an excellent 2,2-diphenyl-1-picrylhydrazyl (DPPH) scavenging activity with an IC50 of 6.65 µg/mL. The C-AgNps showed exceptional antibacterial properties against S. aureus, B. subtilis, P. aeruginosa, and E. coli using a good diffusion assay. The C-AgNps also showed outstanding anticancer properties against A375 human skin malignant melanoma. Thus, the C-AgNps could be used as antimicrobial and anticancer agents for novel therapeutics after lead optimization and in-vivo clinical trials.
