AMPPD is a substrate for alkaline phosphatase (ALP), the enzyme that catalyzes the remotion of the phosphoryl group of AMPPD, triggering light emission. This study investigated the impact of albumins on the AMPPD:ALP system and found that human serum albumin (HSA) increases the light emission efficiency of AMPPD:ALP by around 100 times. The efficiency of light enhancement varied depending on the type of albumin, with bovine (BSA), porcine (PSA), and rabbit (RSA) serum albumins being less effective than HSA. We conducted experiments to demonstrate that once hydrolyzed by ALP, the dephosphorylated AMPPD diffuses to site I of HSA. By studying the photophysical properties of the phenol ester generated after AMPPD cleavage, we found that its complexation with HSA caused a significant increase in its fluorescent efficiency, which explains the amplification of the chemiluminescence. Resonance energy transfer from the excited phenol ester to coumarin-153 was detected, confirming the presence of both molecules in the protein cavity. Hence, introducing fluorescent acceptors into the reaction system can adjust the emission wavelength.

The UiO-66-S-FeS catalyst exhibited a “shell-core” structure, with FeS firmly anchored to the surface of UiO-66-SH₂ via Fe-S bonds, creating a robust interface. The interface significantly enhanced the rate of photogenerated carrier transfer and separation during photocatalytic reactions. While retaining the original advantages of active site dispersion and high specific surface area of MOFs, the doping of FeS resulted in good visible light absorption performance. Ultraviolet–visible diffuse reflectance spectroscopy (UV–Vis DRS) revealed that the visible light absorption scope of UiO-66-S-FeS_0.5 was effectively broadened compared to UiO-66-SH₂. It resulted in a remarkable improvement in tetracycline degradation, achieving a degradation rate of 99.5 % under visible light. Electron spin resonance (ESR) and free radical scavenging experiments identified several reactive species, including ·O₂⁻, h⁺, ·OH and ¹O₂ playing roles in the degradation process.

This paper takes a novel approach incorporating the use of Fe₂O₃-modified TiO₂ (Fe₂O₃/TiO₂) coated polyethylene (PE) foam fruit nets to enhance the shelf life of those mangoes. Various aspects of the study include identifying characterization techniques used in Fe₂O₃/TiO₂. The synthesized TiO₂ particles were analyzed for particle size distribution and size to get the optimum properties for the coating effectiveness. The study examined the methylene blue (MB) degradation mechanism. A UV–Vis spectrometer was used to determine the optical properties of the Fe₂O₃-modified TiO₂, SEM was used to analyze the surface of the coated PE foam nets, indicating even distribution and strong adhesion of the TiO₂ particles. An energy-dispersive X-ray spectroscopy (EDS) test was performed together with an SEM analysis to determine the content of conductive elements and to ensure that Fe was modified into the TiO₂ structure. This research confirms that Fe₂O₃/TiO₂ coatings effectively increase mangoes’ shelf life through their negative impact on microbial growth and the slowing of other ripening processes. Fe₂O₃/TiO₂ at the maximum concentration of 1.0 % w/v further showed a considerable shelf-life extension of 130.23 % to the control sample without coating. Experimental results revealed that the Fe-modified TiO₂ materials performed better in MB degradation tests than unmodified TiO₂. The study also established that the photocatalytic effect of TiO₂ is improved upon Fe modified because the bandgap is also reduced hence improved antimicrobial efficacy when exposed for a short time under fluorescent light. As a contribution to solving the problem of food waste and disease control in technology after the harvest, this study has identified the possibility of using Fe₂O₃/TiO₂ coatings. Further work should also concentrate on enhancing the use of coating to fit the requirements for large-scale application of this technology.</div></div>","PeriodicalId":16782,"journal":{"name":"Journal of Photochemistry and Photobiology A-chemistry","volume":"465 ","pages":"Article 116341"},"PeriodicalIF":4.1,"publicationDate":"2025-02-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143446003","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}
