Scanning Electron Microscopy (SEM) was employed to visualize and qualitatively assess damage to the ultrastructure of S. aureus biofilms cultivated on plastic coverslips after exposure to UV-radiation. The results of the study revealed that the high-energy wavelengths of UV-B and UV-C could effectively induce apoptosis with no evidence of intact biofilm formation after exposure. Therefore, such wavelengths of UV-radiation may be employed as a supplementary mechanism for targeted biofilm decontamination to further minimize the occurrences of biofilm-related nosocomial infections.en-USUltraviolet radiationBiofilmArticlehttps://doi.org/10.48497/6j53-ns25
