Foil backing without nanofibers and foil-backed 100% acetate nanofibers lacked effective antibacterial properties. On three different days (Table 1), samples of plain aluminum foil, aluminum foil-backed 100% acetate nanofibers, and aluminum foil-backed acetate nanofibers containing 30% (by weight) full-spectrum hemp extract were run in parallel. Viable S. aureus were recovered from each sample after a 4 h incubation at 37 °C. The percent increase of viable bacteria, as compared to initial load applied, is displayed. Error bars show standard error of the mean
