Hence, the timely detection of the biomarkers using the optical probes is a useful technique for the disease detection or early-stage prediction of a disease. Although, one of the major hurdles for this technique is the biocompatibility of the probe. In this regard, peptides are excellent choice considering their biocompatibility. Moreover, peptides are one of the most widely explored adaptable molecular templates for fabricating probes to detect biomarkers. Peptidyl templates are advantageous due to their easy synthetic methodologies, adoptable flexible structures and target selectivity. For example, various peptide-based sensors for the detection of nucleic acids including over-expressed miRNA, DNA, and RNA have been used over the decades. Numerous peptide-based enzyme-responsive biosensors, peptide conjugates have been widely explored for the detection of several therapeutically relevant overexpressed enzymes like cathepsin-B. The main focus of this review is to provide a concise overview on the recent developments for the peptide-based fluorescent probes to detect various biomarkers.","PeriodicalId":145,"journal":{"name":"Chemistry - An Asian Journal","volume":" ","pages":"e00211"},"PeriodicalIF":3.5,"publicationDate":"2025-06-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144300800","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Here, we introduce and validate a unified metric, the femtosecond thermal lens integrated magnitude (FTL-IM), to characterize such mixtures. The FTL-IM, derived from the integrated signal area, provides a direct, model-free measure of the total thermo-optical response, including critical convective effects. Applying the FTL-IM to complex six-component accords, we demonstrate its utility in predicting a mixture's thermal response from its composition through linear additivity with respect to component mole fractions. Our method quantifies the accords' behavior, revealing both the baseline contributions of components and the dominant, non-linear effects of highly active species like methyl anthranilate. This consistency is validated across single-beam Z-scan, dual-beam Z-scan, and time-resolved FTLS measurements. The metric also demonstrates the necessity of single-beam measurements for interpreting dual-beam data. This work establishes a rapid, quantitative method for fragrance analysis, offering advantages for quality control by directly linking a mixture's bulk thermo-optical properties to its composition.","PeriodicalId":145,"journal":{"name":"Chemistry - An Asian Journal","volume":" ","pages":"e00521"},"PeriodicalIF":3.5,"publicationDate":"2025-06-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144300802","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Colorimetric sensing of the analyte is investigated, akin to the spectrophotometric absorption principle. Iron in the sample is measured by the formation of orange-colored ferroin resulting from the 1,10-phenanthroline reaction. The reaction scheme is designed to be pH-specific, simple, quick, and effective in detecting trace amounts of iron in real sample matrices without employing any tedious route of synthesis and its characterization. A digital photoresistive prototype is fabricated using a light-emitting diode (LED) and a light-dependent resistor (LDR) to measure the concentration of iron much less than the recommended value by the World Health Organization (WHO). The limit of detection (LOD) is reported to be 0.017 mg L-1, the lowest to date for the class of point of care (POC) devices. The sensor was tested on 55 real-life samples and exhibited good accuracy with UV-vis and AAS measurements with an average absolute % error of 3.258%-14.34%.

The Fe3O4 films are characterized using XRD, Raman spectroscopy, and UV-vis pectroscopy, confirming phase purity. Subsequently, the Fe3O4 thin films are subjected to sulfurization under varying conditions to synthesize iron pyrite (FeS2) thin films, a promising solar absorber material for photovoltaic applications. The sulfurized FeS2 thin films are analyzed for phase purity using XRD, XPS, and Raman spectroscopy, while FESEM was employed to study their morphology. UV-vis-NIR spectroscopy reveals high absorption coefficients (∼105 cm-1 for wavelengths below 700 nm) and indirect bandgaps ranging from 0.78 to 0.86 eV. All films exhibited n-type conductivity with a charge carrier density of ∼1019 cm-3.

Optical and electrochemical analyses revealed that the composite facilitates efficient electron-hole separation (supported by reduced PL intensity and lower charge-transfer resistance in EIS) while retaining strong redox potentials, consistent with an S-scheme charge-transfer mechanism. Additionally, the increased surface area (BET) and porosity further promote reactant adsorption.
