Histogram of antibacterial activity of daptomycin bisphosphonic acid covalently bound to the surface of Ti6Al4V foils. 1: daptomycin modified foils adhered by wax, covered by 200 μL of broth containing 3×105 cfu S. aureus; 2: non-adhered daptomycin modified foils floating in 200 μL of broth containing 3×105 cfu S. aureus; 3: adhered blank foils incubated with 200 μL of broth containing 3×105 cfu S. aureus; 4: 200 μL of broth containing 3×105 cfu S. aureus. Symbol * indicates statistically significant differences (p<0.05) from the other groups. The y-axis is the optical density of the bacteria-containing broth at 600 nm.
