Photoswitchable AIE nanoprobe for lysosomal hydrogen sulfide detection and reversible dual-color imaging

Fusion of aggregation-induced emission and photochromics for promising photoresponsive smart materials

“…87 So far, only a few AIE-active photoswitchable fluorescent chemosensors have been designed. 29,65,88 As an example shown in Fig. 5C, 16a exhibited multi-stimuli-responsive property with multiple colors in the solid and solution states.…”

Fluorescent AIE-Active Materials for Two-Photon Bioimaging Applications

“…As a signal gas transmitter, H 2 S plays a vital role in regulating the different functions of life systems (Hong et al, 2018 ; Lv L. et al, 2020 ; Wang J. et al, 2020 ; Zhang D. et al, 2020 ). Yoon's group developed a two-photon AIE probe 1 based on the mechanism of excited-state intramolecular proton transfer (ESIPT) for fluorescent turn-on detection of H 2 S ( Figure 2A ) (Chen et al, 2017 ).…”

Recent progress in H2S activated diagnosis and treatment agents

“…Some fast and accurate ratiometric uorescent probes for detecting H 2 S have been developed based on FRET. 74,75 Zhao et al 76 developed a self-assembled micelle aggregate NanoBODIPY uorescent probe with H 2 S-triggered FRET switch, which consists of a dynamic energy receptor semi-cyanine-BODIPY hybrid dye (BODInD-Cl) and a complementary energy donor (BODIPY1). In the absence of H 2 S, a specic FRET from BODIPY1 to BODInD-Cl occurs due to the spectral overlap between the emission spectrum of the donor and the absorption spectrum of the acceptor.…”
