Assessment of the biocompatibility, targeted imaging, and photothermal effect in vitro. a Cytotoxicity of PEG-Au@SiNRs. b LSCM images of CT-26 and 4T1 cells after incubation with RGD-Au@SiNRs (blocking with free peptides or not) or Au@SiNRs for 2 h at 37 °C. Scale bars, 25 μm. c Cell viability of CT-26 cells, which were first incubated with RGD-Au@SiNRs or Au@SiNRs for 4 h and then irradiated by an 808-nm laser (0.8 W cm⁻²) for 5 min as mean ± SD (n = 3). Asterisk (**) indicates p < 0.01

Photothermal therapy and safety assessment. a Photographs of representative mice before and after the treatment with different agents and NIR irradiation. b Growth curves of tumor volumes of mice groups with NIR irradiation. c Weight of the excised tumors from the PTT-treated mice. d Survival curves of PTT-treated mice. e Serum biochemistry data including alkaline phosphatase, alanine aminotransferase, and aspartate aminotransferase, and blood urea nitrogen levels of control and RGD-Au@SiNRs-treated healthy mice. f Complete blood counts: hematocrit, hemoglobin, mean corpuscular hemoglobin, mean corpuscular hemoglobin concentration, mean corpuscular volume, blood platelets, red blood cells, blood levels of white blood cells, and platelets of control and RGD-Au@SiNRs-treated healthy mice. g H&E staining of various organ tissues harvested from tumor-bearing mice at the end of treatment. Asterisk (**) indicates p < 0.01; (***) means p < 0.001

Tumor-targeted multimodal imaging in vivo. a Schematic illustration of the active targeting of RGD-Au@SiNRs. b PA imaging and c the corresponding PA signal intensity of tumor regions of CT-26 tumor-bearing mice untreated and treated with RGD-Au@SiNRs, Au@SiNRs, or PBS for 12 and 24 h. d Infrared thermal mapping images, and e corresponding temperature change of tumor regions of CT-26 tumor-bearing mice irradiated with an 808-nm laser (0.8 W cm⁻²) for different times (0–8 min, time interval: 30 s) at 24 h post-administration with RGD-Au@SiNRs, Au@SiNRs, or PBS. f LSCM images of tumor sections at 24 h post-injection of PBS, Au@SiNRs, or RGD-Au@SiNRs. Scale bars, 100 μm, and g corresponding quantitative analysis of the fluorescence intensity. h The bio-distribution of RGD-Au@SiNRs and Au@SiNRs measured by ICP-OES at 24 h post-administration. Asterisk (**) indicates p < 0.01; (***) means p < 0.001
