AI Article Synopsis
- A new fluorescent sensor was created to simultaneously detect aluminum (Al) and hydrogen peroxide (HPO) through changes in fluorescence intensity.
- The sensor can detect Al and HPO at very low concentrations, specifically 0.83 µM for Al and 1.7 µM for HPO, and operates with a 1:1 binding ratio for both substances.
- Its effectiveness was validated through various scientific methods, including spectroscopy and test strips, showing that the sensor can repeatedly identify Al and HPO in sequence.
Article Abstract
A novel acylhydrazone-based fluorescent sensor was designed and synthesized for consecutive sensing of Al and HPO. displayed fluorometric sensing to Al and could sequentially detect HPO by fluorescence quenching. The limits of detection for Al and HPO were determined to be 0.83 and 1.7 μM, respectively. The binding ratios of to Al and -Al to HPO were found to be 1:1. The sequential recognition of Al and HPO by could be repeated consecutively. In addition, the practicality of was confirmed with the application of test strips. The sensing mechanisms of Al and HPO by were investigated through fluorescence and UV-Visible spectroscopy, Job plot, ESI-MS, H NMR titration, and DFT calculations.
