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

Figure 7

Surface affinity of MNPs to S. aureus and E. coli postexposure at different time intervals. MNPs were collected with external magnet and optical density of the remaining solution was measured spectrophotometrically. Data was recorded as percentage reduction in optical density at time interval of three independent tests.
