SEM Analysis of Surface Impact on Biofilm Antibiotic Treatment

Figure 1

Evolution of the amount of viable cells within 24-hour biofilms formed on GLA (black circles) and SIL (grey circles) during exposure to ampicillin. Statistically significant differences between the materials (for a confidence level greater than 99%, < 0.01) are pointed as . The means ± SDs for three independent experiments are illustrated.
