Background: With the development of nanotechnology, there has been a tremendous growth in the application of nanoparticles for drug delivery systems, antibacterial materials, cosmetics, sunscreens, and electronics. Titanium dioxide (TiO2) nanoparticles (NPs) are manufactured worldwide for a variety of engineering and bioengineering applications. TiO2 NPs under ultraviolet radiation produce a strong oxidative effect through the formation of above-mentioned reactive oxygen species and can be used as a photocatalytic disinfectant without other chemical reagents.
Aim: To
assess the antioxidant activity of grape seed mediated titanium dioxide
nanoparticles.
Materials and
Methods: The collected fruit seeds were washed dried powdered and subjected to
nanoparticles synthesis by adding titanium oxide solution to the grape seed
extract solution. The solution was centrifuged and checked for absorbance using
the spectrometry. The antioxidant property of the extract was evaluated using
the DPPH (2, 2-diphenylpicrylhydrazyl) assay. The results were analyzed and
graphs were plotted.
Results: The
titanium nanoparticles showed strong spectrophotometric absorbance around 370
nm. When subjected to DPPH assay to check for its antioxidant activity, grape
seed mediated titanium oxide nanoparticles showed highest antioxidant activity
at a concentration of 50 μl (80%).
