New Non Phyto- and Eco-Toxic Alumina-Stabilized Silver and Praseodymium Nanoparticles



In the present study, we examined how the active aluminum nano-oxide in the gamma form used as a neutral carrier for the nanoparticles of various metals (as Ag, Pr) affected their toxic behavior. Our experiments have shown that exposure to metal nanoparticles can be reduced by binding the nanoparticles to alumina nanoparticles and the aluminum nano-oxide is suitable to function as the nano-stabilizer for the Ag and Pr nanoparticles. We have managed to manufacture new alumina-stabilized silver and praseodymium nanoparticles using dry sol-gel method that are not phyto- and eco-toxic.
