- A fast responsive chromogenic and near-infrared fluorescence lighting-up probe for visual detection of toxic thiophenol in environmental water and living cellsPublication . Wu, Juanjuan; Su, Dongdong; Qin, Caiqin; Li, Wei; Rodrigues, João; Sheng, Ruilong; Zeng, LintaoThiophenols as high toxic environmental pollutants are poisonous for animals and aquatic organisms. Therefore, it is indispensable to monitor thiophenols in the environment. Herein, a novel near-infrared fluorescent probe was developed for the detection of thiophenols, which was easily prepared by one-step coupling of 2,4-dini trobenzenesulfonyl chloride with Nile blue. The probe showed a significant near infrared (∼675 nm) fluores cence “turn-on” response to thiophenols with some good features including chromogenic reaction, high sensi tivity and selectivity, fast response, near-infrared emission along with low detection limit (1.8 nM). The probe was employed to rapidly and visually determine thiophenols in several industrial wastewaters with good re coveries (90–110%). Moreover, this probe has been demonstrated good capability for imaging thiophenol in HeLa cells
- Chemical sensors towards environmental toxic molecule monitoring: fluorescent probes for detection of thiophenolPublication . Jiang, Lirong; Wu, Juanjuan; Min, Douyong; Rodrigues, João; Sheng, RuilongThiophenols, a family of important industrial chemicals, is highly toxic for aquatic organisms and human beings. Developing new chemical sensors with the merit of fast, low cost, portable, selective and sensitive, as well as visualizable signal output for efficient detection of thiophenols, is highly desirable. This spotlight article reviewed and discussed the current trend and statement of thiophenols-specific fluorescent probes. Moreover, the future outlook in this field was also stated.
