Silver nanoparticles are extensively being studied for various applications in different fields. Functionalized silver nanoparticles are now being used as drug carriers. Ascorbic acid (Vitamin C) is a well-known antioxidant which has been reported to have various beneficial properties to humans. Here we have synthesized silver nanoparticles functionalized with ascorbic acid. The functionalized nanoparticles were further coated with PEG. The nanoparticle synthesis was characterized using UV-Visible spectral analysis, XRD, FTIR and Scanning electron microscope. The average size of the nanoparticle was found to be 24 nm. The synthesized nanoparticle was found to possess antioxidative effects.

Antioxidative Effects

Oxidative stress has been implicated as critical pathogenic factors contributing to the etiology of diabetic retinopathy and other retinal diseases. This study investigated antioxidative effect of ascorbic acid and astaxanthin on ARPE-19 cells within an oxidative stress model induced by common biological sources of reactive oxygen species (ROS). Hydrogen peroxide (H2O2) at concentrations of 0.1–0.8 mM and 20–100 mJ/cm2 of ultraviolet B (UVB) were treated to ARPE-19 cells. Cell viability and intracellular ROS level changes were measured. With the sublethal and lethal dose of each inducers, 0–750 μM of ascorbic acid and 0–40 μM of astaxanthin were treated to examine antioxidative effect on the model. Ascorbic acid at concentrations of 500 and 750 μM increased the cell viability not only in the UVB model but also in the H2O2 model, but 20 and 40 μM of astaxanthin only did so in the UVB model. The combination of ascorbic acid and astaxanthin showed better antioxidative effect compared to each drug alone, suggesting a synergistic effect.
