Aydin, Duygu; Gunay, Ibrahim Berk; Karuk Elmas, Sukriye Nihan; Savran, Tahir; Arslan, Fatma Nur; Sadi, Gokhan; Yilmaz, Ibrahim published the article 《A simple and sensitive fluorescent sensor platform for Al3+ sensing in aqueous media and monitoring through combined PET and ESIPT mechanisms: practical applications in drinking water and bio-imaging》. Keywords: fluorescent sensor aluminum bioimging.They researched the compound: 2-Furoic hydrazide( cas:3326-71-4 ).Product Details of 3326-71-4. Aromatic heterocyclic compounds can be divided into two categories: single heterocyclic and fused heterocyclic. In addition, there is a lot of other information about this compound (cas:3326-71-4) here.
In this study, a novel hydrazide-based compound, (E)-N′-(5-(benzo[d]thiazol-2-yl)-2-hydroxybenzylidene)furan-2-carbohydrazide (probe BOTH, I) was designed, characterized and prepared as a fluorogenic “”turn-on”” sensor for monitoring Al3+ in near-perfect aqueous media. All emission and absorbance spectral studies were performed in HEPES/DMSO (volume/volume, 99.95/0.05, pH = 7.0) media at 25 °C. The quantum yield of probe BOTH increases considerably in the presence of Al3+. Probe BOTH could sense Al3+ at a concentration as low as 6.47 nM. Probe BOTH could sense Al3+ with high sensitivity and selectivity, and a quant. correlation of R2 = 0.9887 in the Al3+ concentration range of 0.0-20.0 equivalent To evaluate the method parameters, a validation study was performed based on different anal. parameters. The formation of complex BOTH-Al3+ (2 : 1 stoichiometry) was confirmed by 1H-NMR titration and MALDI-TOF MS, as well as Job′s methods. pH-Dependent and Benesi-Hildebrand plot studies also supported this proposed sensing mechanism. Besides, the binding mechanism of Al3+ with probe BOTH was further verified by theor. studies. Moreover, probe BOTH could be used for monitoring Al3+ in living-cells and water samples.
There is still a lot of research devoted to this compound(SMILES：O=C(C1=CC=CO1)NN)Product Details of 3326-71-4, and with the development of science, more effects of this compound(3326-71-4) can be discovered.
