Effect of Surface Charge and Hydrophobicity Modulation on the Antibacterial and Antibiofilm Potential of Magnetic Iron Nanoparticles

Figure 6

Growth kinetics of S. aureus (a and b) and E. coli (c and d) in absence and presence of different concentrations of OA-MNPs (a and c) and APTMS-MNPs (b and d). Bacterial cells were exposed to different concentrations of the MNPs (15.625, 31.25, 62.5, 125, and 250 μg/mL) at different time intervals compared to untreated control cells. Independent triplicate experiments were carried out for each reaction; error bar represents the standard deviation of mean.
