Chemically, pure TiO2 and TiO2-doped Bi2O3 nanoparticles are synthesized using the low temperature hydrothermal method. The properties of the synthesized nanoparticles were studied using various characterization methods. In addition to powder X-ray diffraction (PXRD) and scanning electron microscopy (SEM), energy-dispersive X-ray spectroscopy (EDAX), transmission electron microscopy (TEM), selected area electron diffraction (SAED), and Fourier transform infrared (FTIR) analyses, we studied the structural and surface morphology of the nanoparticles. By analyzing those data, we can determine the average crystallite size, strain, crystallinity, the molecular composition, the grain size of the nanoparticles, the structure, shape, functional groups, and types of bonds between them. Electrochemical impedance spectroscopy (EIS) and cyclic voltammetry (CV) analyses were used for electrochemical studies. Based on these data, a study was conducted on charge transfer and specific capacitance. Photoluminescence (PL) and ultra-visible absorbance (UV–vis) spectra were used to determine the optical properties. Based on these spectra, it is possible to determine the optical bandgap of the particles and their potential as photocatalysts. Under a visible light radiation source, pure TiO2 and TiO2-doped Bi2O3 nanocomposites were used in the photocatalytic degradation of malachite green (MG) and Rhodamine-B (RhB) dyes. By studying the observations, we were able to determine the degradation efficiency, as well as the rate constant. Results showed that the TiO2-doped Bi2O3 nanocomposites showed an increase in degradation efficiency of ~0.8% for RhB dye and ~27.7% for MG dye when compared to pure TiO2 nanoparticles.","PeriodicalId":49902,"journal":{"name":"Luminescence","volume":"40 4","pages":""},"PeriodicalIF":3.2,"publicationDate":"2025-04-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1002/bio.70161","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143749846","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Early diagnosis and treatment of HCC can effectively reduce mortality. Carboxylesterase (CE) is abundantly present in liver tissue, which shows promise as an innovative diagnostic biomarker for HCC. Herein, we designed and synthesized a novel fluorescent probe BDPPh-CES, based on a boron dipyrromethenes (BODIPY)-styryl framework, for the ratiometric detection of CE. Upon interaction with CEs, the probe demonstrates a characteristic fluorescence emission red shift, completing the reaction within 30 min. Notably, BDPPh-CES maintains specificity against acetylcholinesterase (AChE) and various biological species, while exhibiting robust performance across physiological pH conditions. Comprehensive mechanistic investigations, combining high-resolution mass spectrometry (HRMS) analysis, density functional theory (DFT) computational studies, and molecular docking simulations, provided insights into the binding and sensing mechanisms. The high sensitivity and low cytotoxicity facilitated real-time ratiometric imaging of CEs at the cellular level, successfully distinguishing elevated CE expression in Hepa 1–6 hepatic cancer cells over AML 12 normal hepatocytes.
