Exosome-decorated Bio-heterojunctions Reduce Heat and ROS Transfer Distance for Boosted Antibacterial and Tumor Therapy

Photothermal and photodynamic therapies represent effective modalities for combatting bacteria and tumor cells. However, therapeutic outcomes are constrained by limitations related to the heat and reactive oxygen species (ROS) transfer distance from photosensitizers to targets. To address this issue, we have devised and developed exosome-decorated bio-heterojunctions (E-bioHJ) consisted of MXene (Ti
