In this work, silver nanoparticles (AgNPs) were elaborated using a simple, low cost and reproducible method, by thermal treatment at 90 °C of chitooligosaccharides (COS), produced by chitosan depolymerization using the digestives chitosanases from Portunus segnis viscera, in the presence of AgNO3. The obtained AgNPs were characterized using UV–visible spectroscopy, transmission electron microscopy (TEM), dynamic light scattering (DLS) and Fourier transform infrared spectroscopy (FTIR) analyses and compared to chitosan-AgNPs. Moreover, the biological properties of the synthesized AgNPs were evaluated, proving that they exhibited interesting antioxidant and antibacterial activities. The present investigation suggested that COS will be a good source for the preparation of AgNPs that could be useful in different industrial and biomedical applications.
Keywords: chitooligosaccharides, bioactive silver nanoparticles, physicochemical properties, antioxidant activity, Antibacterial activity
