Why are Silver Nanoparticles More Toxic Than Bulk Silver? Towards Understanding the Dissolution and Toxicity of Silver Nanoparticles
The mass-transport to a spherical particle in solution is considered in the context of the mechanism of oxygen reduction on silver nanoparticles. For small particles (≤1 μm) the reduction follows a two-proton, two-electron pathway due to the rapid diffusion of the intermediate hydrogen peroxide away...
