Abstract:
A D-D'-A-D'-D''-D'-A-D'-D type photoactive oligomer (O-BT) based nanoparticles (NPs) were prepared for biomedical application. The O-BT NPs possessed a high extinction coefficient, excellent hyperthermia generation ability, satisfactory NIR-II fluorescence emission, and good batch-to-batch reproducibility, and could be used as high-efficiency phototheranostics for photothermal therapy and NIR-II fluorescence imaging.
