Fluorescence Recognition of H₂S by a Benzothiazole Derivative and Its Live Cell Imaging

Mitochondria-Targeted Red-Emission Fluorescent Probe for Ultrafast Detection of H2S in Food and Its Bioimaging Application

“…Huang et al developed a fluorescent method for evaluating the H 2 S releasing capacity of 10 organosulfur-rich fruits and vegetables . In our previous work, we also reported several novel near-infrared (NIR) emission probes for detecting H 2 S with fluorescence “off–on” response in wine. − Although the probes synthesized by us have realized facile synthesis and multiple applications, they still have the following problems: (1) long reaction time (20–170 min), which is unable to realize rapid detection; (2) only applying to wine samples using the standard additions method; and (3) only detecting exogenous H 2 S in cells, which cannot be targeted to mitochondria, which is the main site for the production of endogenous H 2 S. , Therefore, developing advanced probes with fast-response, detecting actual food samples, and mitochondria-targeted properties is highly demanded to meet these challenges in food and biological samples.…”

Triazine Derivative for Fluorescence Sensing of Zr4+, Fe3+ Ions and Acetone

“…[27,28] However, up to now, there is only a small amount of detection of Zr 4＋ ion, [29] mostly the recognition of Fe 3＋ ion by Zr(IV)-MOFs. [30,31] Besides, MOFs are also used as fluorescent probes to detect small molecular compounds, such as H 2 S, [32] biomolecules, [33] acetone [34,35] and nitroaromatic compounds. [36～38] Therefore, there is an urgent need to develop a new chemosensor for the rapid selective and sensitive detection of Zr 4＋ , Fe 3＋ ion and acetone as the replacement.…”
