a CLSM images of tumor tissues in the Lewis tumor-bearing mice after injection of AuNRBR/N, AuNRBR and PBS. Blue fluorescence: nuclei, red fluorescence: BODIPY. The ratio of administered neutrophils in the total neutrophils in tumor after intravenous injection of AuNRBR/N labeled with DiD at 4, 8, 12, 24 and 48 h. The percent showed by b representative flow cytometry data and cindividual histograms. Scale bar: 100 μm.*p < 0.05 and **p < 0.01 vs the 12 h group
