Cytotoxic Effect of Chitosan Based Nanocomposite Synthesized by Radiation: In Vitro Liver and Breast Cancer Cell Line

A silver nanoparticle (AgNP) is likely to provide an attractive object for combining a variety of biochemical properties with great therapeutic potential by using radiation. The present study explores the IC50 value of chitosan-poly (vinyl alcohol) hydrogel (Cs/PVA) and Ag-doped chitosan-poly (vinyl alcohol) (Cs/PVA/Ag) nanocomposite in view of their anticancer application. The aim was to develop (Cs/PVA) based hydrogel synthesized by gamma radiation which could behave both as a nanoreactor for Ag nanoparticle with promising anticancer applications. The (Cs/PVA/Ag) nanocomposite was confirmed by FTIR (Fourier transform infrared) spectroscopy, XRD (X-ray diffraction) and EDX (energy dispersive X-ray) analysis. The anti-cancer activity of the prepared nanocomposites was demonstrated in human liver cancer cell line (HEPG2) and breast cancer cell lines (MCF7). It has significant effects against human liver cancer cell line HEPG2 compared to breast cancer cell line MCF7. Further quantitative analysis on the molecular and protein levels is still required to confirm the impact of chitosan on genotoxic effect before reaching a final conclusion and starting its biomedical application.
