ZnO nanoparticles of different sizes were functionalized with an amphipathic peptide, and its
effect on nanoparticle stabilization and UV photoprotective activity was studied in this article.
The peptide-modified nanoparticles exhibited lower aggregation, significant reduction in
Zn2+ leaching in vitro and even inside the cells for smaller particle sizes, reduced
photocatalytic activity, and reduced cellular toxicity under UV-B treated conditions. In
addition, the peptide-modified 60 nm ZnO nanoparticles showed lower genotoxicity, lower …
