- BODIPYs are highly potential photoactive agents for cancer theragnostics. The rational design of BODIPYbased photoactive nanodrugs with high efficiency and near-infrared (NIR) absorption is imperative.
- A donor–acceptor–donor (D–A–D) organic photosensitizer (PS) (BODIPY, named NBB), which possessed strong absorption in the NIR region due to the multi-intersection of intramolecular charge transfer (ICT), photoinduced electron transfer (PET), and heavy atom effects.
- Through a nanoprecipitation method, NBB nanoparticles (NPs) were facilely prepared. The as-prepared NBB NPs exhibited favorable water-stability and photostability.
- The outstanding photon absorption capacity endows the NPs with high photothermal conversion efficiency (Z = 53.8%) and active singlet oxygen (1O2) generation ability upon 808 nm laser irradiation.
