(A) Schematic illustration of combined ultrasonic imaging and enhanced photothermal therapy with CuS-ST68 MBs through UTMD. (B) In vitro US contrast-enhanced images in a latex tube before and after CuS-ST68 MBs injection in PIHI contrast mode and B-mode. The CuS-ST68 MBs could be disrupted to lose imaging capability (red circled area) through UTMD upon enhanced US, showing the potential of targeted delivery of CuS NPs to tumor. (C) Concentration-dependent photothermal temperature elevation upon exposure to NIR light (808 nm, 2 W). (D) HeLa cell viability after treatment with different concentrations of CuS-ST68 MBs with or without NIR laser irradiation. Reproduced with permission from Ref. 63.
