This sensor exhibits an “On–Off–On” detection cycle to detect Cu2+, Zn2+, and S2− in solution. According to the chelation-enhanced fluorescence (CHEF) mechanism, when Zn2+ is present, the fluorescence is significantly enhanced and a blue shift occurs, representing a “Turn-On” phase of the fluorescence detection mode. Because copper ions (Cu2+) have a paramagnetic quenching sensing mechanism, the fluorescence of L quenches rapidly with the formation of the L-Cu system, representing the “Turn-Off” phase. The subsequent introduction of S2− to the L-Cu system results in the recovery of the L-fluorescence, thereby representing the second “Turn-On” phase. As a peptide molecule, the sensor L has several advantages over other types of sensors, including water solubility, high sensitivity, and good biocompatibility, with a very low detection limit. The detection lines of Zn2+ and Cu2+ are 97 nM (R = 0.993) and 75 nM (R = 0.995), respectively. Additionally, the sensor does not exhibit any obvious cell toxicity.

Ce4+, possessing oxidization, could directly oxidize o-phenylenediamine (OPD) to form the yellow fluorescent product oxOPD. Under the excitation wavelength of 370 nm, oxOPD had a maximum fluorescence emission at 562 nm. Meanwhile, due to the occurrence of the inner filter effect (IFE), oxOPD quenched the fluorescence of N,S-CDs. However, ascorbic acid (AA) inhibited the oxidation of Ce4+, causing the fluorescence of oxOPD at 562 nm to decrease, accompanied by an increase in the fluorescence belonging to N,S-CDs at 450 nm. Thus, a Ce4+-assisted ratiometric fluorescence method was established for AA detection.

Even after reviewing the literature extensively, no one has documented a method for estimating baclofen using microwave-assisted stability-indicating spectrofluorimetric techniques, despite the abundance of options for baclofen stability, assay, and bioanalysis. Organic solvents, which are typically necessary for current procedures but may be costly and toxic, have a severe effect on aquatic life and the environment. Using green solvents and 4-chloro-7-nitrobezofuran as a fluorescent probe, this work conducted a stability-indicating spectrofluorimetric estimate of baclofen. Through the use of a design-of-experiments technique, a reliable microwave-aided spectrofluorimetric method was developed, with little solvent consumption and time for sample analysis. Prior to conducting response surface analysis and optimizing important variables and responses, a fractional factorial design was used to screen method variables and responses. A central composite design was then employed for these purposes. This flexible spectrofluorimetric technique was used to assess baclofen concentrations in forced degraded samples and marketed formulations. For baclofen determination, the suggested spectrofluorimetric approach was found to be green, quick, easy to use, economical, and user-friendly.","PeriodicalId":49902,"journal":{"name":"Luminescence","volume":"39 10","pages":""},"PeriodicalIF":3.2,"publicationDate":"2024-09-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142331246","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
