The molecule shows an appreciable change in absorption and emission spectra at 75% water-acetonitrile mixture compared to pure acetonitrile. In water-acetonitrile mixture, it displays aggregate-induced emission (AIE) bands. New emission peaks are observed at 560 nm and 630 nm, corresponding to LE (locally excited) and ICT (intramolecular charge transfer) states of CBZ-BDP aggregates. The fluorescence anisotropy studies of CBZ-BDP in glycerol medium show its better sensitivity towards the microenvironment. CBZ-BDP was used to probe various microheterogeneous systems like bile salts, pluronics, and lipid bilayer systems in aqueous medium. The dye displays sensitive variation in emission intensity and fluorescence anisotropy in sodium cholate (NaC) bile salt in aqueous medium as a function of the bile salt concentration. The molecule detects the temperature-induced phase transitions in pluronic P123 and F127, as well as 1,2-dimyristoylphosphatidylcholine (DMPC) and 1,2-dipalmitoylphosphatidylcholine (DPPC) lipid bilayer systems in aqueous medium. These studies strongly suggest that CBZ-BDP can be used as an efficient fluorescent probe in sensing the micro-environmental changes in bile salts, pluronics, and lipid bilayers in aqueous medium. The imaging studies of CBZ-BDP-embedded Giant Unilamellar Vesicles (GUVs) were carried out. The molecule stains the lipid bilayers and displays bright-green fluorescent images, suggesting its potential in lipid bilayer imaging.","PeriodicalId":98,"journal":{"name":"Photochemical & Photobiological Sciences","volume":" ","pages":""},"PeriodicalIF":2.7,"publicationDate":"2024-12-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142870584","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}

The probe exhibited a unique fluorescence response to hypochlorous acid and had good anti-interference performance in the presence of other interference. When HTD met the NaClO, the light orange fluorescence was changed to green with the blue-shifted emission wavelength from 550 to 500 nm. Moreover, the absorbance of HTD's UV-vis at 300 nm and 375 nm decreased in the presence of NaClO. The limit of detection was 1.83 × 10-7 M and 2.96 × 10-6 M based on the fluorescence and UV-vis titration data. NMR, HRMS, and IR spectra suggested that the possible sensing mechanism of HTD to NaClO was the formation of initial compound 4-(3-formyl-4-hydroxyphenyl) benzonitrile due to the oxidation of hypochlorous acid in aqueous solution. The portable test strips were obtained, and the real water sample test reached good results with spiking recoveries among 92.00% ~ 103.25%. Finally, endogenous hypochlorous acid produced by LPS and PMA was successfully detected by HTD in living mice using in situ fluorescence bioimaging.","PeriodicalId":98,"journal":{"name":"Photochemical & Photobiological Sciences","volume":" ","pages":""},"PeriodicalIF":2.7,"publicationDate":"2024-12-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142862608","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}

This manuscript reviews the environmental concentrations and potential toxicity of various UVF. The highest concentrations of UVF are typically observed near frequently visited recreational areas and during peak water-activity periods, which suggests that sunscreen application correlates with noticeable alterations in UVF concentrations. Aquatic concentrations of certain filters have sporadically exceeded 10 μg/L, although most measurements remain below 1 µg/L, which is below commonly reported toxicity levels. UVF have also been detected in aquatic organisms, typically ranging from nondetectable levels to a few hundred ng/g, depending on the species. The toxic effects from UVF, such as coral bleaching and diminished growth, have been observed in laboratory settings, however, toxicity tends to manifest only at significantly higher levels than what is typically detected in aquatic environments. Further research is imperative to provide consumers with improved guidance on selecting sunscreen containing UVF that poses the least environmental risk.","PeriodicalId":98,"journal":{"name":"Photochemical & Photobiological Sciences","volume":" ","pages":""},"PeriodicalIF":2.7,"publicationDate":"2024-12-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142862609","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}

In the UV-Vis spectra, a bathochromic shift in the absorption bands of both hydrazones was observed following the addition of cyanide. These spectral changes were accompanied by a color transition from transparent to orange for L1 and from pale yellow to peach for L2, which is attributed to the deprotonation of the chemosensors. The detection limits for cyanide ions were determined to be 0.36 µM for L1 and 2.79 µM for L2 using the 3σ rule. Quantum chemical calculations were employed to optimize the structure of the chemosensors, compute their UV-Vis spectra, and confirm the proposed detection mechanism for CN⁻ ions.","PeriodicalId":98,"journal":{"name":"Photochemical & Photobiological Sciences","volume":" ","pages":""},"PeriodicalIF":2.7,"publicationDate":"2024-12-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142826746","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}

We demonstrate that collective mode formation under modal coupling between localized surface plasmon resonances (LSPRs) with a chiral arrangement and Fabry-Pérot (FP) nanocavity modes can induce chiroptical responses. We fabricated a cluster of isotropic gold nanodisks with a chiral arrangement (gold nano-windmills, Au-NWs) on the FP nanocavities of TiO2 and Au film. The differential absorption of the Au-NWs coupled with the FP nanocavities under left- and right-handed circularly polarized light irradiations in the far field was significantly enhanced compared with the differential absorption without the FP nanocavities. Far- and near-field analyses by numerical simulation revealed that the Au-NWs coupled with the FP nanocavities formed a collective mode in the near field, and the collective mode represented the chiroptical response in the far field. The light field with the large helicity, can be used in chiral light-matter interactions. The concept of collective mode formation using isotropic metal nanodisks coupled with FP nanocavities provides a platform for controlling complex light fields.","PeriodicalId":98,"journal":{"name":"Photochemical & Photobiological Sciences","volume":" ","pages":""},"PeriodicalIF":2.7,"publicationDate":"2024-12-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142798740","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}

Recent enhancements make PDT outpatient-friendly and less discomforting. Effectiveness hinges on selecting the appropriate PS. This article delves into natural and synthetic PSs, emphasizing the rising interest in natural alternatives for their safety. It explores their mechanisms, characteristics, and applications, offering insights into their potential contributions to advancing PDT. This extensive review delves into the preclinical and clinical landscape of natural PSs for PDT, shedding light on their diverse applications and promising outcomes. Compounds like curcumin, piperine, riboflavin, psoralen, hypericin, and others show significant potential in preclinical in vitro studies across various cell lines. In vivo, these photosensitizers prove effective against skin tumors, carcinomas, and sarcomas, inducing apoptosis, autophagy, and ROS generation for therapeutic efficacy. The review underscores the critical role of proper dosing and monitoring in balancing therapeutic benefits and risks. It highlights the advantages and limitations of natural PSs, emphasizing their specific targeting, bioavailability, and limited side effects. The future of PDT holds promising breakthroughs, taking from some evidence like Bergamot oil in nanostructured lipid carriers for dermatological conditions. Second-generation photosensitizer Tookad shows potential in prostate cancer treatment, while Tripterygium wilfordii Hook.

The high electron-hole recombination was found out for composites photocatalysts, which significantly influences only on organic compounds decomposition in solutions. However, there is no direct dependence between effective photodegradation of simple organic molecules and antimicrobial properties. Inactivation of bacteria is determined by many factors such as active generated radicals, adsorption properties of the surface and the photocatalyst form, which can change the main active radicals.
