Abstract
Zinc and copper metal nanoparticles were produced from bulk metal rods by an underwater high-voltage discharge method. The metal nanoparticles, with estimated diameters of 1 nm to 2 nm, were determined to be more than 85 % non-oxidized. Exposure of rat RG2 glioma cancer cells to these nanoparticles resulted in morphological cell changes, including decreased cell adherence, shrinking/rounding, nuclear condensation and budding from cell bodies. The nanoparticles were lethal for the cells at the sub-nanomolar concentrations.
