Highlights of NanoAmor ZnO Nanopowders Used in Research: Zinc oxide nanoparticles, in suspension form, were used by L. Zhang et al. as antibacterial agents against the E. Coli disease-causing bacterium . The ZnO particles actually damage the E. Coli's membrane walls, while also being generally regarded as safe for human beings and animals. By studying the effect of varying particle sizes and concentration, the authors found that as one decreases the ZnO's diameter, the bacteriostatic activity is improved. Further advantages are brought by an increased ZnO concentration. Finally, the authors also note that dispersing the solution via PEG (polyethylene glycol) or via PVP (polyvinylpyrolidone) polymers allows for an improvement in solution stability, while at the same time maintaining the antibacterial benefits of ZnO. Such results have great promise for industries such as food, textiles, packaging and healthcare, as nanostructured inorganics' high-temperature, high-pressure stability begins to be fully exploited.
