Ultrasound induced biosynthesis of silver nanoparticles embedded into chitosan polymers: Investigation of its anti-cutaneous squamous cell carcinoma effects

Here we have shown the novel biosynthesis of silver nanoparticles (Ag NPs) encapsulated by chitosan polymers in the presence of aqueous extract (Ag NPs@CHI). The Ag ions were first embedded over the chitosan surface enriched with polar organofunctions like amines (NH ) and hydroxyls, and subsequently the ions were reduced green-metrically by the electron rich phytochemicals of the plant extract. After the synthesis numerous techniques, including the UV-vis spectrum, transmission electron microscopy, FE-SEM, EDS-elemental mapping, and ICP-AES, were used to study the physicochemical characteristics of the nanocomposite biomaterial. Next, we explored the material biologically in the anti-cutaneous squamous cell carcinoma effects against the corresponding cell lines like PM1, MET1, MET 4, SCC T9, SCC IC1MET, SCC IC19, SCC T8, and SCC T11. The related IC values of the nanocomposite against them were 182, 158, 177, 178, 177, 99, 62, and 183 µg/mL, respectively. The cytotoxicity in terms of percentage cell viability of cancer cells were decreased with the increase in the nanocomposite doses.
