A Safer Nanotechnology

Nanotechnology has blossomed for over a decade as evidenced by the growing number of applications of nanomaterials. Environmental implications are an important consideration when developing new materials and researchers in Saudi Arabia have developed a more environment friendly way to make nanomaterials from zinc oxide.¹ Their approach avoids using toxic volatile organic solvents and allows them to make zinc oxide nanorods for medical and other uses in nothing more than hot water.
