A device was developed to study the evolution of fluorescence spectra as a function time. previously designed fluorimeter based on diode array mini-spectrometer CM12880MA used. The control and measurement were carried out by programming SAM21D microcontroller. Considerations regarding optimization acquisition speed, memory, computer interface have been analyzed optimized. As result, very versatile with great adaptability, reduced dimensions, portability, low budget (under EUR 500) has built. sensitivity, controlled integration time photodiodes, can be adjusted between 10 µs 20 s, thus allowing sampling times ranging from ms more than h. Under these conditions, chemical rate constants s−1 10−8 experimentally determined. It wide operating range for kinetic constant determination, over six orders magnitude. proof system performance, oxidation reaction Thiamine in basic medium form fluorescent Thiochrome employed. emission spectrum followed, decomposition measured at 2.1 × 10−3 s−1, value which matches those values reported literature this system. calibration curve also performed, obtaining detection limit 13 nM, consistent data. Additionally, stability tested, being photo-decomposition 1.8 10−4 3.0 10−7 presence absence UV light (365 nm), respectively. Finally, experiments obtain, single measurement, both constants: formation its under non-fluorescent product. obtained are good agreement through independent same experimental conditions. These results show that, considered an unstable intermediate successive stages.

AbstractMercury, a highly toxic heavy metal, poses significant environmental and health risks, necessitating the development of effective responsive techniques for its detection. Organic chromophores, particularly small molecules, have emerged as promising materials sensing Hg2+ ions due to their high selectivity, sensitivity, ease synthesis. In this review article, we provide systematic overview recent advancements in field fluorescent chemosensors detection, including rhodamine derivatives, Schiff bases, coumarin naphthalene BODIPY, BOPHY, naphthalimide, pyrene, dicyanoisophorone, bromophenol, benzothiazole flavonol, carbonitrile, pyrazole, quinoline, resorufin, hemicyanine, monothiosquaraine, cyanine, pyrimidine, peptide, quantum/carbon dots probes. We discuss detection capabilities, mechanisms, limits well strategies approaches employed design. By focusing on studies conducted between 2022 2023, article offers valuable insights into performance detection.Keywords: Chemosensorfluorescent probeHg2+ions AcknowledgmentsThe author express sincere gratitude Principal D.B.S.

Supramolecular chemistry is a relatively new field of study that utilizes conventional chemical knowledge to produce edges smart materials. One such material use supramolecular the development sensing platforms. Biologically relevant molecules need frequent assessment both qualitatively and quantitatively explore several biological processes. In this review, we have discussed techniques with key examples kinds bio-analytes tried cast light on how molecular design can help in making Moreover, these materials been finally used as platforms has well. Several useful spectroscopic, microscopic, visible, electronic outcomes sensor discussed, special emphasis device-based applications. This kind comprehensive discussion necessary widen scope technology.
