a Transwell assay results of RAW264.7 cells towards RM-1 tumor cells in vitro. The migrated RAW264.7 cells were stained with violet crystal. b Temperature changes of PBS and aqueous dispersions of MAs-DOX/PEG-BPEI-rGO with different PEG-BPEI-rGO concentrations after 5-min NIR irradiation at a power density of 1 W/cm2. c The cell viability index of RM-1 cells treated with free DOX, MAs-DOX/PEG-BPEI-rGO centrifugation medium and irradiated MAs-DOX/PEG-BPEI-rGO centrifugation medium. The untreated RM-1 cells were used as control. Results are represented as mean ± SD (n = 3). *p < 0.05, **p < 0.01, NIR treated MAs-DOX/PEG-BPEI-rGO compared with untreated MAs-DOX/PEG-BPEI-rGO (two-tailed Student’s t-test)
