Figure 1From: Diameter-sensitive biocompatibility of anodic TiO2 nanotubes treated with supercritical CO2 fluidSEM images of self-organized TiO 2 nanotubes with different diameters. The nanotubes are in the range of 15 to 100 nm before (a to d) and after (e to h) the ScCO2 treatment. Disordered Ti(OH)4 precipitates are indicated by white arrows.Back to article page
