ALB and cancer: The release study was conducted in the serum at 37 °C, where approximately 70% of ICG was released from the HSA–ICG–PFTBA after 12 h of incubation, which was significantly higher than that of the CCm–HSA–ICG–PFTBA (approximately 20%, P < 0.001, Fig. 2b), indicating that cancer cell membrane coating conferred stability and lowed ICG leakage of this nanoprobe.
