Firstly, the pristine BiON was prepared, via two types of solvent, by using a hydrothermal method. In the case that water was used as a solvent, the BiON.W photocatalyst with a pine-like structure was obtained. However, by using mixed solvent (comprising ethanol: water of 20:80), the BiON.M photocatalyst with a flower-like morphology was achieved. Secondly, the binary BiON-AgBr heterostructure was then constructed using a chemical precipitation technique. Accordingly, the photocatalytic performance of the prepared BiON-AgBr photocatalyst was evaluated through the photodegradation of Rhodamine B (RhB) dye under natural sunlight irradiation. The synthesized BiON-AgBr photocatalyst still exhibits high photocatalytic efficiency, even after three consecutive cycles of use. Trapping experiment revealed that the superoxide anion radicals (^•O₂⁻) play the most important role in RhB removal. The result suggested a Z-scheme mechanism based on AgBr/Ag/BiON. The formation of metallic silver (Ag⁰), upon sunlight illumination, was proved as the evidence shown in the XRD pattern of the used photocatalyst. The synergistic effect of the Z-scheme heterojunction and the surface plasmon resonance (SPR) of silver metal results in the considerable enhancement of the sunlight-driven photodegradation of RhB dye and the remarkable improvement of the disinfection of <em>E. coli</em> bacteria.</div></div>","PeriodicalId":37785,"journal":{"name":"OpenNano","volume":"24 ","pages":"Article 100249"},"PeriodicalIF":0.0,"publicationDate":"2025-06-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144307060","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This study aims to develop and evaluate edible coatings that contain nano-chitosan and lemongrass essential oil nanoemulsions as antioxidant and antimicrobial agents for fruit packaging. The synthesized lemongrass essential oil nanoemulsion size was less than 100 nm and had good stability with a below 10% size change during 56 days of storage. Lemongrass essential oil nanoemulsion had a high antioxidant activity, as indicated by the low IC₅₀ value in the DPPH reagent test. The combination of lemongrass essential oil nanoemulsion and chitosan as an edible coating had high antimicrobial activity, as indicated by the large inhibition zone in <em>Bacillus cereus</em> and <em>Escherichia coli</em> bacteria. Edible coating implementation on unpeeled banana fruit was evaluated through various tests such as pH, hardness, weight loss, and color changes. These tests showed some improvement in fruit preservation using nanoemulsion-based edible coatings treatment. The bananas were observed for 11 days and showed that the edible coating made from the combination of chitosan and lemongrass essential oil nanoemulsion can delay the ripening process of fruits, maintain firmness, and reduce weight loss.

Effective TDDS must consider drug properties (molecular weight, solubility, and lipophilicity), vehicle composition, and skin characteristics (hydration, temperature, and regional permeability) to overcome these limitations. Chemical permeation enhancers interfere with the lipid matrix of the stratum corneum, and natural permeation enhancers, including essential oils and terpenes, provide other alternatives.
