Abstract
The “Green” synthesis of metallic nanoparticles and investigation of their optical properties has become a useful application between nanoscience and medicine. In this work, silver nanoparticles (Ag-NPs) were successfully prepared through a facile and green method by treating silver ions with chitosan. Preparation of Ag-NPs in silver nitrate solution (0.01 M) resulted in small and spherical shapes of Ag-NPs with a mean diameter of 10.2 nm. The formation of Ag-NPs was approved by surface Plasmon resonance (SPR) absorption peaks, using UV-vis spectrophotometer, while Ag-NPs were successfully employed in colorimetric sensing of H2O2 via an analytical procedure. Degradation process of Ag-NPs, encouraged by the catalytic decomposition of H2O2, causes a significant change in the absorbance intensity of SPR band depending on the H2O2 concentration. The cytotoxicity effect of synthesized Ag-NPs was examined on HEK293 cell line. The results illustrate a concentration-dependent toxicity for the tested cells, while15.07 μg/mL of IC50 was obtained.
