Biofluorescence in living entities is a functional process associated with information conveyance; whereas the capacity to respond to internal physiological signals is a unique property of a cell. By integrating these two biological features into materials design, a bioinspired material, namely CPS, is developed. Contrary to conventional luminescent polymeric systems whose emission comes from π‐conjugated structures, this material displays clusterization‐triggered emission. In the preclinical trial on a dermal punch model of tissue repair, it successfully increases the rate of wound closure, reduces inflammatory cell infiltration, and enhances collagen deposition. It can also relay changes in internal chemical signals into changes in its intrinsic luminescence for biphasic chemical sensing to prevent possible occurrence of skin hyperpigmentation caused by minocycline hydrochloride in wound therapy. Together with its ease of fabrication, high biocompatibility, high drug loading efficiency, and high release sustainability, CPS shows high potential to be developed into an intelligent solid‐state device for wound treatment in the future.
In article number 2001267, Wing‐Fu Lai and co‐workers develop a bioinspired and luminescent material which can respond to internal signals to enable biphasic monitoring of the drug delivery process. Together with its ease of fabrication, high biocompatibility, high drug loading efficiency, and high release sustainability, this material shows high potential to be developed into an intelligent solid‐state device for wound treatment in the future.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
