Bacterial adhesion on antibiotic-releasing nanopillar surface. SEM images showing adhesion of S. aureus on a, d smooth electropolished Ti; b, e 2D TiO2 nanopores; and c, f 3D TiO2 nanopillars surfaces, without (top-row) and with (bottom-row) gentamicin-tannic acid coating. b Shows bacterial attachment on 3D nanopillar top and gaps between pillar bundles. f The red marking indicates an extracellular polymeric substance excreted by bacteria. g Schematic representation of bacterial adhesion on tannic acid/gentamicin coated 3D nanopillars. Scale bar a–f represents 1 µm. Adapted with permission from ref. 145
