Time-lapsed bacterial killing and glucan degradation by ferumoxytol-activated H2O2. a Bacterial cells are labelled in blue by SYTO 60 and dead cells in purple by propidium iodide (n = 4). High-magnification close-up views of (b, c) single bacterial cell showing nanoparticles (labelled with Alexa Fluor 488, in yellow; upper/lower panels) bound to its surface (Scale bar: 1 µm). d Time-lapsed EPS glucans (labelled in red with Alexa Fluor 647-dextran conjugate) degradation by ferumoxytol-mediated H2O2 catalysis (n = 4) (Scale bar: 100 µm)
