Fig. 3From: Nanostructured surface topographies have an effect on bactericidal activityCharacterization of S. aureus viability on various nanostructured surfaces by fluorescence microscopy after SYTO9/PI staining. Fluorescent images a–f were obtained on the nanostructured surfaces S(a)–S(f) shown in Fig. 1, respectively. Green and red colors indicate live and dead cells, respectively.
