This study demonstrates the antioxidant properties of gold nanoparticles in various sizes, suggesting new applications for oxidative stress reduction.
Key Points
The antioxidant activity of gold nanoparticles increases with finer particle sizes, and they show significant efficiency in scavenging free radicals.
In the DPPH assay, the films exhibited a maximum percentage inhibition of 43.91%, indicating robust antioxidant capabilities.
Structural analysis confirmed the formation of a face-centered cubic structure with a crystallite size of 19 to 31 nm, which influences antioxidant efficacy.
These findings highlight the potential of gold nanoparticles as effective agents against oxidative stress-related conditions.
