a In vivo NIRF images and (b) thermographic images of the mice bearing abscess intravenously injected with f-Ag⁺-GCS-PDA@GNRs at a dose of 4.7 mg/Kg at 0, 2, 4, 6 and 24 h post-injection. For the thermographic images, the test mice were irradiated under 808 nm near-infrared light (0.8 W cm⁻², 6 min) at different time points after intravenous injection. c Corresponding NIRF intensities determined from Fig. 5a. d NIRF images of heart, liver, spleen, lung, kidney, and abscess extracted from the test mice intravenously injected with f-Ag⁺-GCS-PDA@GNRs at 24 h post-injection. e Quantitative amount of the Au and Ag in the major organs and abscess at 24 h post-injection. f Infrared thermography (0.8 W cm⁻², 6 min) and (g) temperature elevations of the mice bearing abscess intravenously injected with Ag⁺-GCS-PDA@GNRs at a dose of 4.7 mg/Kg at 6 h post-injection. * and ** present p < 0.05 and p < 0.01, respectively
