Description
A polymeric coating incorporating metal or metal‑oxide nanoparticles that actively kills bacteria on food surfaces.
Technical
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.
