Research Abstract

Carcinogenesis of nanoparticles remains uncertain despite nano-sized materials are widely used. In this study, liver carcinogenesis of nano- and micro-sized particles (Copper oxide;CuO, Titanium dioxide ; TiO_2) was examined after exposure of three different routes. Consequently, these results indicate that nanoparticles have promoting potential on the liver carcinogenesis.
