Physiochemical features of RBCM-cRGD, HNP and HNP@RBCM-cRGD in aqueous dispersions. A TEM images of RBCM-cRGD, HNP (red arrow), and HNP@RBCM-cRGD (scale bar = 100 nm). B The illustration of HNP synthesis. C DLS and zeta potentials of RBCM-cRGD, HNP, and HNP@RBCM-cRGD in aqueous dispersions (0.1 mg/mL, error bars represent the mean ± s.d.). D SDS-PAGE analysis of the RBCM-related proteins in RBCM-cRGD and HNP@RBCM-cRGD. E Western blotting analyses of RBCM marker. F Absorption spectra of RBCM-cRGD, HNP and HNP@RBCM-cRGD in dispersions (0.1 mg/mL). G Infrared thermal images of PBS, RBCM-cRGD, HNP, and HNP@RBCM-cRGD (0.5 mg/mL) under the irradiation of an 808 nm laser (1.0 W/cm2) for 0 s, 30 s, 60 s, 90 s, 120 s, 150 s, and 180 s. H Temperature curves of PBS, RBCM-cRGD (0.25 mg/mL), HNP (0.2, 0.5 mg/mL), and HNP@RBCM-cRGD (0.5 mg/mL) in aqueous dispersion under irradiation of the 808 nm laser at 1.0 W/cm2. I Photothermal stability of HNP and HNP@RBCM-cRGD (808 nm laser, 3 cycles, 1.0 W/cm2, 0.5 mg/mL)
