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

Figure 4

Inhibitory potential of MNPs (MNPS, OA-MNPS, CA-MNPs, Arg-MNPs, A-MNPs, and APTMS-MNPs) prepared as 100 μg/mL on S. aureus and E. coli after 24 h treatment based on CFU assay method. Bar chart represents the mean bacterial count × 10⁸ after treatment by each MNP species (charge displayed in mV) as compared to control.
