In vivo outcomes of MW irradiation. a FLIR images monitoring temperature changes of tumors site during the MW ablation. b PCNA staining results in the peripheral ablation area. ①: control, ②: free DOX, ③: NaCl–DOX@PLGA, ④: MW, ⑤: MW + NaCl@PLGA, ⑥: MW + NaCl–DOX@PLGA. The scale bar is 50 μm. c tumor volume growth curve in different groups. d HE results of control tumor (①), local tumor progression (②), and complete ablation (③–④). e The tumor harvested at the end of observation. f survival rate curve of nude mice
