As one of the important intracellular organelles, the Golgi apparatus (GA) serves as the primary site for protein synthesis. Cysteine is involved in protein formation and metabolism and other activities in cells, so its concentration is directly related to the proper function of the GA. Therefore, the development of a highly selective and sensitive method to detect the concentration of cysteine in the Golgi apparatus has important biomedical significance for diagnosing diseases. In this study, a naphthalimide-dicyanoisophorone conjugate was utilized as the fluorescent unit, benzenesulfonamide as the Golgi-localizing group, and acrylate as the recognition moiety to construct a Golgi-targeted near-infrared probe for Cys detection. When Cys was absent, the intramolecular charge transfer (ICT) effect was suppressed, resulting in minimal fluorescence emission from the probe. However, upon the addition of Cys, the ICT process was restored, inducing an enhancement in the NIR fluorescence emitted by the probe. Within the level scope from 0.2 μM to 10 μM, the fluorescence intensity of the probe demonstrated a linear correlation with the level of Cys. Furthermore, the limit of detection was determined as 0.024 μM. The fluorescent probe for Cys demonstrated excellent selectivity, superior sensitivity, rapid response time, and a broad pH working scope.

It was shown repeatedly that the interpretation of kinetic data in the photocatalytic ox/redox reactions is not an easy task. The well-developed microporous structure, unlike that of standard heterogeneous catalysis, is not always the necessary feature. A very fine porous structure brings a significant part of the active surface. However, it is not usually available for photons. When hit the surface, they form reactive species that then diffuse deeper into the catalytic particle. However, the process becomes more driven by mass transport and the reaction rate measurement no longer takes place in the kinetic regime. This limitation can be avoided by using light-sensitive materials that offer a sufficiently developed surface, but only to the extent that it is directly accessible to the incident photons. Here, such a type of thin-film catalyst is described, and porogenic camphor is used to create a suitable surface morphology and porosity. The roles of camphor content and additional plasma treatment were experimentally verified. All coatings were described with a battery of techniques with a focus on their structural and morphological properties. The coatings were then employed in a tetracycline oxidation in a slit-type micro-photoreactor. Their performance was compared with chemically identical structures, however, obtained without the porogenic body, and/or the additional plasma treatment. The chosen transformation of tetracycline represents both a suitable model reaction and a process of general relevance in the decontamination of wastewater containing pharmaceuticals.</div></div>","PeriodicalId":16782,"journal":{"name":"Journal of Photochemistry and Photobiology A-chemistry","volume":"468 ","pages":"Article 116507"},"PeriodicalIF":4.1,"publicationDate":"2025-05-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144124200","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}
