Fig. 6From: Bactericidal effects and accelerated wound healing using Tb4O7 nanoparticles with intrinsic oxidase-like activitya The hemolysis ratio of red blood cells. The insert images of tubes containing red blood cells solution show the direct observation of hemolysis. Tube 1: PBS buffer; Tube 2–5: 25, 50, 100, and 200 μg/mL Tb4O7 NPs; Tube 6: ultrapure water. b MTT assays determined cell viability of HUVECs after Tb4O7 NPs treatmentBack to article page
