A Illustration of RONS scavenging by PB NZs. B O2 generation by different indicated sample solutions at 37 °C. C The production of O2 bubbles in different solutions after reaction for 10 min in PBS (pH 7.4). The units of H2O2 and PB NZs are wt% and µg/mL, respectively. D ·OH scavenging ability of PB NZs at different concentrations. E O2.− free radical scavenging ability of PB NZs at different concentrations. F Free radical-scavenging ability of PB NZs at different concentrations evaluated by an ABTS assay. G Antioxidant ability of PB NZs against different concentrations of DPPH. H Absorption spectra of DPPH solution with 200 µg/mL PB NZs added, from 0 to 50 min. I Time-dependent absorbance at 550 nm of DPPH alone or treated with 200 µg/mL PB NZs
