comments from Sonovia regarding zinc: With regards to Sonovia's use of metallic nanoparticles, Zinc oxide nanoparticles are recognised as GRAS by FDA (Generally safe for use). At the extremely low concentrations we use they cannot cause toxicity in human body systems. In fact daily intake of zinc via food is needed to carry out the regular metabolic functions. Our nanoparticles are approximately 240 microns in size which is not of the dimensions able to enter cells and exert any effects.

(Since zinc oxide nanoparticles up to a concentration of 100 μg/ml are harmless to normal body cells, they can be used as an alternative to antibiotics). Silver as mentioned, had a different biochemical pattern and is not of discussion here. With regard of nano-particles used in our fabrics, they remain locked into the fabric by our sono process for 90+ washes (our product has a usage life of 1 year). We will be running further studies to examine the reduction in nanoparticles in the fabric and their effects, so that we can safely and effectively maximise shelf-life of the product commercially for our consumers. We are also currently applying through EUA for FDA approval of the SonoMask.
Properties of Zinc Oxide Nanoparticles and Their Activity Against Microbes
Zinc oxide is an essential ingredient of many enzymes, sun screens, and ointments for pain and itch relief. Its microcrystals are very efficient light absorbers in the UVA and UVB region of spectra due to wide bandgap. Impact of zinc oxide on biological ...
