Cytotoxic effect of the PITMS NP coatings on HaCaT cells measured by the LDH assay. Cells (3 × 105) were incubated with the supernatant of the various films that were pre-incubated in the medium according to the experimental section. Cells were incubated with Triton-x-100 1 % as positive control (100 % toxicity). Untreated cells (negative control) were similarly incubated. Each bar represents mean ± SE of 4 separate samples
