报告摘要:

Switchable phototheranostic nanomaterials are of particular interest for specific biosensing, high-quality imaging, and targeted therapy in the field of precision nanomedicine.1Here, we develop a “one-for-all” nanomaterial (NanoPcTBs) that self-assembles from flexible and versatile phthalocyanine building blocks.2Fluorescence and reactive oxygen species (ROS) generation could be triggered depending on a targeted, protein-induced, partial disassembly mechanism, which creates opportunities for low-background fluorescence imaging and activatable photodynamic therapy (PDT). We also reported a facile strategy to directly assemble a phthalocyanine photosensitizer (PcS) with an anticancer drug mitoxantrone (MA) to form uniform nanostructures (PcS-MA), which have the capability of undergoing nucleic acid-responsive disassembly.3On the other hand, thein vivospecific binding between albumin and PcS, arising from the disassembly of injected NanoPcS, was recently confirmed using an inducible transgenic mouse system.4In addition, we demonstrated that a new, nanostructured phthalocyanine assembly, NanoPcA, inherently possesses the ability to promote highly efficient ROS generation via the type I mechanism.5Finally, recent progress from our group on the fluorescent probes based onN-heterocyclic carbene (NHC) boranes for HOCl6will be also presented.
