What You Need to Know
Silver nanoparticles release Ag⁺ ions that disrupt bacterial membranes and DNA, while zinc‑oxide nanoparticles generate reactive oxygen species under UV‑A illumination, oxidizing cellular components. The coating is applied at elevated temperatures to ensure uniform dispersion and cured to lock the nanoparticles in place, enabling long‑term antimicrobial activity at low storage temperatures.
The Science
Primary Reaction
