Fig. 9. In vivo monitoring of the change of casp-3 (A) and casp-9 (B) activities on subcutaneous HeLa tumor-bearing mice after injection with the nanoprobe (100 μL) and irradiation with 808 nm laser for 30 min using the left nanoprobe-injected mouse as control. (A) Excitation: 661 nm; emission: 680–800 nm. (B) Excitation: 455 nm; emission: 500–620 nm.
