Metal nanoparticles (MNPs), due to its increasingly wide applications in consumer products, raises its concern towards ecotoxicology. Once released into the environment, the zero-valent metal (M°) readily oxidized to ionic metal (M + ) which is reported as the main source of toxicity related to MNPs...
