WebNov 1, 2024 · A simple and portable photothermal method for biothiols was designed. • The polydopamine nanoparticles with photothermal effects were formed on the surface of ZIF-67. • Biothiols could “weaken” the photothermal signal through decomposition of ZIF-67. • The proposed sensor possessed high sensitivity and specificity for biothiols. • WebJan 5, 2024 · In this paper, a photoinduced electron transfer (PET)& twisted intramolecular charge transfer (TICT)-based fluorescent probe (1) for detecting biothiols (GSH/Cys/Hcy) and hydrogen sulfide with fluorescence turn on was developed.The probe could recognize hydrogen sulfide over primary ions and selectively detect GSH/Cys/Hcy over other amino … WebNov 3, 2016 · The optical response of Probe 1 for biothiols was investigated in HEPES buffer (10.0 mM, pH 7.4) with 30% CH 3 CN. As shown in Fig. 2, Probe 1 featured an absorption band with a maximum at 498 nm and was almost non-fluorescent. The addition of excessive Cys to the solution of Probe 1 resulted in a 26 nm blue-shift from 498 nm to … chrome pdf 转 图片
