Figure 8From: Bactericidal activity and biocompatibility of ceragenin-coated magnetic nanoparticles P. aeruginosa cell disruption under MNP-CSA-13 treatment, evaluated using atomic force microscopy. Images recorded before (A) and after CSA-13 (B), MNP (C) and MNP-CSA-13 (D) addition. Analysis of cell surface topography showed increasing membrane roughness and leakage of the intracellular contents.Back to article page
