Article Synopsis
- - The new probe (DN) detects hydrogen sulfide (HS) using a chemical reaction that generates a noticeable color change from yellow to pink and produces red fluorescence in specific conditions.
- - DN shows excellent performance with a low detection limit of 15.1 nM and a quick response time of 5 minutes, making it effective for sensing HS.
- - A test kit using paper strips was created for checking meat freshness by detecting HS, and DN can also visualize HS in live cells, aiding research on its link to clinical diseases.

Background: Speech analysis has been expected to help as a screening tool for early detection of Alzheimer's disease (AD) and mild-cognitively impairment (MCI). Acoustic features and linguistic features are usually used in speech analysis. However, no studies have yet determined which type of features provides better screening effectiveness, especially in the large aging population of China.

A novel Schiff-base fluorescent probe, 4-(N-(2- hydroxyl-1-naphthalymethylimino)-ethylamino) -7-nitro-1,2,3-benzoxadiazole (HENB) was synthesized and utilized for spectral sensing of Fe ions at neutral pH. The binding of Fe to HENB in CHOH-HEPES buffer (1:1 v/ v, 25 mM, pH 7.2) resulted in a pronounced emission enhancement at 530 nm, which is possibly due to the inhibition of photo-induced electron transfer (PET) process as well as the chelation enhanced fluorescence (CHEF) effect.
