Field-emission scanning electron microscopy (FE-SEM) micrographs and Energy dispersive X-ray (EDX) spectra illustrating: (A) formation of solids by interaction of silver nitrate with artificial human sweat constituents; (B) no appreciable change in the morphology of individual commercially available metallic silver nanoparticles; (C) EDX spectra demonstrating that solids formed from reactions of silver nitrate in artificial sweat were silver and chlorine; and (D) EDX spectra demonstrating that following immersion of silver nanoparticles in artificial human sweat, particles were silver and chlorine.
