Size-dependent intratumoral behavior of NMs. A schematic illustration of the disassembly of BiS@HSA/DTX mNRs and DTX release upon laser exposure. B TEM images and schematic pictures (insets) of BiS@HSA/DTX mNRs before (left) and after (right) laser irradiation (808 nm, 1 W/cm², 10 min). C PA visualization of tumors in mice with or without laser irradiation at 12 h p.i. D fluorescence images of tumor-bearing mice obtained at various time points with or without laser exposure.
