Fluorescent probes and functional materials for biomedical applications

摘要

Due to their simplicity in preparation,sensitivity and selectivity,fluorescent probes have become the analytical tool of choice in a wide range of research and industrial fields,facilitating the rapid detection of chemical substances of interest as well as the study of important physiological and pathological processes at the cellular level.In addition,many long-wavelength fluorescent probes developed have also proven applicable for in vivo biomedical applications including fluorescenceguided disease diagnosis and theranostics(e.g.,fluorogenic prodrugs).Impressive progresses have been made in the development of sensing agents and materials for the detection of ions,organic small molecules,and biomacromolecules including enzymes,DNAs/RNAs,lipids,and carbohydrates that play crucial roles in biological and disease-relevant events.Here,we highlight examples of fluorescent probes and functional materials for biological applications selected from the special issues“Fluorescent Probes”and“Molecular Sensors and Logic Gates”recently published in this journal,offering insights into the future development of powerful fluorescence-based chemical tools for basic biological studies and clinical translation.
