Human safety review of "nano" titanium dioxide and zinc oxide

Based on the current weight of evidence of all available data, the risk for humans from the use of nanostructured titanium dioxide (TiO(2)) or zinc oxide (ZnO) currently used in cosmetic preparations or sunscreens is considered negligible. There is a large body of information that when viewed in its entirety is considered as sufficient to demonstrate that these nanostructured ultraviolet (UV ...

Zinc oxide nanowires on carbon microfiber as flexible gas ...

· Among the various oxides studied, zinc oxide (ZnO) is one of the most common materials used as a gas sensor due to its high change in electrical resistance, as well as for its stability, safety and biocompatibility. Recently, quasionedimensional (1D) nanostructures, such as nanowires, nanorods, nanobelts, and nanotetrapods, have been reported to show even higher responses compared with …

Zinc oxide nanorod sensor Wikipedia

A zinc oxide nanorod sensor or ZnO nanorod sensor is an electronic or optical device detecting presence of certain gas or liquid molecules ( humidity, NO, hydrogen, etc.) in the ambient atmosphere. The sensor exploits enhanced surface area (and thus surface activity) intrinsic to all nanosized materials, including ZnO nanorods. Adsorption of molecules on the nanorods can be detected ...
