In vivo tissue penetration recovery analysis in pHIFU-treated femoral tissue. a, b Fluorescence images of femoral tissues, which rested for 0, 1, and 3 h after treatment of 0, 20, and 50 W pHIFU. The fluorescence signal was monitored at 30 min after intravenously injecting of FCNPs. Scale bar indicates 1 mm. c Relative fluorescence intensity of FCNPs in femoral tissues. ** indicates difference at the p < 0.001 significance level
