Figure 2 Examples of flow cytometric for E. faecalis exposure to nanoparticles-ZnO, TiO 2 , and SiO 2 at concentration of 0.2 mg/ml. Fluorescence (FL1-H/FL3-H) was tested from bacterial cells inside gate P1 in a FSC-H (forward scatter-H)/SSC-H (side scatter-H) density plots. Live bacterial cells (gate P2); dead bacterial cells (gate P3). Effect of bacterial concentrations on quantification of bacteria after exposure to nanoparticles In this experiment, we further investigated interference of nanoparticles ZnO (0.5 mg/ml), TiO2 (0.5 mg/ml), and SiO2 (1 mg/ml) on quantifications of S.
