Fig. 1From: Nanostructured surface topographies have an effect on bactericidal activitySEM images of nanostructured Ormostamp surfaces S(a)–S(f) (scale bar: 200 nm). Typical surface structures show nanoscale pillar-like protrusions. The images from left to right columns correspond to high to low pillar density, while those in up and down rows represent large to small pillar height. The structural features of S(a)–S(f) are summarized in Table 1Back to article page
