In recent years, significant advancements have been made in the research of photoswitchable probes. These probes undergo reversible structural and electronic changes upon light exposure, thus exhibiting vast potential molecular detection, biological imaging, material science, information storage. Through precisely engineered structures, can toggle between “on” “off” states at specific wavelengths, enabling highly sensitive selective detection targeted analytes. This review systematically presents fluorescent colorimetric built on various photoswitches, primarily focusing types involving photoswitching their and/or signal response processes. It begins with an analysis including photophysical properties, photoisomerization photochromic mechanisms, fundamental design concepts for constructing The article then elaborates applications these detecting diverse targets, cations, anions, small molecules, biomacromolecules.

Gold nanoclusters (AuNCs) are emerging as promising functional probes for bioapplications. However, because of rapid renal clearance, it is a challenge to tailor their biofate and improve disease-targeting ability in vivo. Herein, we report an efficient strategy organotropic actions by rationally designing AuNC assemblies. The nanocluster assembly established based on the moderate electrostatic interaction or strong coordination between AuNCs, enabled solely chitosan (CS) coadded chelating metal ions (e.g., Gd
