photobleaching under light irradiation. Herein, we design a convenient strategy to load a new kind of NIR-absorbing nonlinear optical (NLO) chromophore FTC-3f with the biocompatiblepolymer, methoxy poly(ethylene glycol)-poly(lactideco-glycolide) (mPEG-PLGA). The resulted FTC-3f/PLGA nanoparticles showed excellent stability, high photothermal conversion efficiency (∼51.11%) and good photoacoustic performance
