Characterization of GSMM. (a) Schematic illustration of the sorting route for MDSCs. (b) Flow images of MDSCs at before or after magnetic cell sorting. (c) TEM images of GNR, GNR@SiO2, GSM and GSMM. (d) Hydrodynamic size distribution of GSM and GSMM measured by dynamic light scattering. (e) Zeta potential of GNR, GSM and GSMM. (f) UV–vis–NIR spectra of GNR, GNR@SiO2, GSM and GSMM. (g) Photothermal images of GSMM in different time points under a 1064 nm laser irradiation (80 μg/mL, 0.6 W/cm2). (h) The heating curve of GSMM with different concentration (0, 10, 20, 40, 80, 100 ppm) under a 1064 nm laser irradiation (0.6 W/cm2). (i) The heating curve of GSMM with different laser powers (0.2, 0.4, 0.6, 0.8, 1.0 W/cm2) under a 1064 nm laser irradiation (80 ppm). (j) The photothermal stability of GSMM after six cycles of laser irradiation “on” and “off”. (k) The heating curve of GSM and GSMM under a 1064 nm laser irradiation (80 ppm, 0.6 W/cm2).
