Penetration depth tunable BODIPY derivatives for pH triggered enhanced photothermal/photodynamic synergistic therapy

Abstract

phototherapy indicates that BDPtriPh NPs with the longest NIR absorbance (813 nm) and highest photothermal conversion efficiency (60.5%) can effectively inhibit tumor growth and reduce side effects to normal tissues. This study provides a strategy to modulate the photoconversion characteristics of PSs for both penetration-depth-tunable and pH-dependent PDT/PTT synergistic cancer therapy in clinics.
