The Claim

The antimicrobial activity of bionanocomposite films increases with higher concentrations of zinc oxide nanoparticles, as demonstrated by larger inhibition zones (e.g., 16±0.5 mm to 33±0.6 mm at 1.5% concentration) compared to lower concentrations (e.g., 4±0.2 mm to 19±0.1 mm at 0.1% concentration).

In plain English

When more zinc oxide nanoparticles are added to special films, they become better at killing germs, which you can see by bigger clear rings around the film where germs can't grow.
