Abstract
Deferasirox based fluorescent probe DSA was accomplished through convenient synthetic method. Probe DSA exhibited the aggregation induced emission enhancement features along with the formation of “J-type aggregates”. Maximum emission wavelenghth of the probe DSA was observed at 505 nm in H2O/DMF. The absoption and emission spectral results of DSA probe were also drawn from the theoretical analysis through time dependent density functional theory (TDDFT). Theoretical spectral results were found exactly similar to the results obtained from experimental studies. The probe DSA sensitively and selectively detected the oxytetracycline showing the limit of detection of 70 nM. Probe DSA demonstrated PET based fluorescence quenching mechanism for sensing of OTC. DSA-OTC interaction was checked through UV–Vis. fluorescence and 1H NMR titration analysis experimentally. The interaction between the DSA and OTC was non-covalent in nature which was further elucidated by performing the density functional theory (DFT) studies. Practical applicabilty was determined in human plasma and milk samples. The finger print identification through DSA was also analyzed under UV light (365 nm). DSA was practically utilized as fluorescent ink.
期刊介绍:
Spectrochimica Acta, Part A: Molecular and Biomolecular Spectroscopy (SAA) is an interdisciplinary journal which spans from basic to applied aspects of optical spectroscopy in chemistry, medicine, biology, and materials science.
The journal publishes original scientific papers that feature high-quality spectroscopic data and analysis. From the broad range of optical spectroscopies, the emphasis is on electronic, vibrational or rotational spectra of molecules, rather than on spectroscopy based on magnetic moments.
Criteria for publication in SAA are novelty, uniqueness, and outstanding quality. Routine applications of spectroscopic techniques and computational methods are not appropriate.
Topics of particular interest of Spectrochimica Acta Part A include, but are not limited to:
Spectroscopy and dynamics of bioanalytical, biomedical, environmental, and atmospheric sciences,
Novel experimental techniques or instrumentation for molecular spectroscopy,
Novel theoretical and computational methods,
Novel applications in photochemistry and photobiology,
Novel interpretational approaches as well as advances in data analysis based on electronic or vibrational spectroscopy.
