The purity determination of neutrophils a not stained or b doubly stained with FITC-CD11b and PE/Cy7 Ly-6G/Ly-6C analyzed by flow cytometry, respectively. The average population of the cells shown in the corner of each quadrant. c Images of purified neutrophil observed by microscope. d, e Neutrophils incubated with FITC-labeled AuNRBR for different time were determinated by flow cytometry and analyzed by mean fluorescence intensity d and observed by fluorescence microscope (e). f The release of AuNRBR from AuNRBR/N when irradiated with an 808 nm laser or not (n = 3). The error bars were presented as mean ± SD (n = 3). Scale bar: 20 μm. **p < 0.01 vs the 60 min group, ***p < 0.001 vs the Light (-) group
