Nanotechnology has been widely used in the development of new strategies for drug delivery and cancer therapy. Compared to traditional drug delivery systems, nano-based drug delivery system have greater potential in a variety of areas, such as multiple targeting functionalization, in vivo imaging, combined drug delivery, extended circulation time, and systemic control release. Nano-systems incorporating...
Tetraphenylethene and doxorubicin are assembled into a self‐indicating drug delivery system (TD NPs). TD NPs are decomposed into DOX and TPE NPs in lysosome. Since TD NPs, TPE NPs and DOX are all fluorescent, the detachment of DOX from TPE NPs is accompanied by fluorescence changing. By observing the fluorescence changes, the spatiotemporal drug release is visualized.
