Characterization and Antitumor Activity of Chitosan/Poly (Vinyl Alcohol) Blend Doped with Gold and Silver Nanoparticles in Treatment of Prostatic Cancer Model

Abstract

The application of nanotechnology in various fields of science has earned a great concern over the past decades. The natural products and surface-modified polymers and metallic nanoparticles (NPs) have evolved as promising nanomaterials for targeted prostate cancer treatment. In the present study, Chitosan/poly (vinyl alcohol) (Cs/PVA) blend was synthesized by gamma radiation which could behave a nanoreactor for silver (Ag) and gold (Au) nanoparticle with promising anticancer applications. (Cs/PVA/Ag) and (Cs/PVA/Au) nanocomposites were confirmed by SEM (scanning electron microscope) and TEM (transmission electron microscope) analysis. The swelling properties have been investigated as a function of time and pH. The anti-cancer activity of the prepared nanocomposites was demonstrated in prostatic cancer cell line. It has a significant effect against prostatic cancer. However, metal nanoparticles have shown a good experimental success in the field of nanomedicine especially in cancer treatment, which has always been an area of high concern. The collaboration of biomedical research in the identification and characterization of biomedical strategies using the interesting metal nanocomposite will impact the future nanomedicine greatly.
