Considering melanin’s wide range of properties, this project aims to combine these and optimize the use of melanin-based products for biomedical applications. In particular, melanin has been found to regulate reactive oxygen species (ROS) and reactive nitrogen species (RNS), toxic by-products that induce tissue damage and are linked to disease mechanisms and aging processes. Melanin regulates ROS and RNS in two ways: 1) it limits radiation-induced ROS and RNS by absorbing a portion of incoming radiation; 2) it neutralizes ROS and RNS already present in tissues. This project aims to investigate these antioxidant properties by synthesizing drug-loaded melanin nanoparticles (MNPs) and investigating their antioxidant potential in mice cancer cells ATCC-CRL3210 using an antioxidant assay kit and α,α-diphenyl-β-picryl hydrazyl assays. In a secondary study, the antioxidant potential of PEG-MNPs will also be determined in the case of radiation exposure. Considering that ROS and RNS production is a common side-effect of cancer treatments, developing an MNP-based drug delivery system may help neutralize those side effects and improve patient treatment and recovery.
