Figure 2. Bactericidal activity of nanowire titania surfaces.

Figure 2

(a) Fluorescence micrographs of P. aeruginosa and S. aureus after one-hour incubations on different surfaces. Bacterial viability LIVE/DEAD® BacLight™ assays simultaneously stain cells with intact (SYTO® 9, green) and damaged (propidium iodide, red) membranes. (b) Average number of stain-dead cells on nanowire surfaces, including gold-plated brush type (black bar), after subtracting the background adhesions (corresponding titanium and gold-coated flat surfaces).
