This study investigated the synthesis of three distinct CuO nanoparticles through the use of aqueous extracts derived from <em>Laurus nobilis</em> L. leaves. The synthesized CuO NPs were characterized using UV–Vis spectroscopy, scanning electron microscopy coupled with energy dispersive spectroscopy (SEM–EDS), transmission electron microscopy (TEM), and Fourier-transform infrared (FTIR) spectroscopy. Surface plasmon resonance bands in the range of 250–285 nm confirmed the synthesis of CuO NPs. FITR spectrometry results revealed CuO-specific vibrations at the 601 cm⁻¹ band. CuO NPs were uniformly distributed, 10–26 nm in size and spherical shaped, as inferred from SEM and TEM images. According to EDS results, Cu content of the nanoparticles was in the range of 3 %–45 %. The antimicrobial activities against gram-positive and gram-negative bacteria, along with yeast, were assessed using the micro-dilution technique. CuO NP1 did not demonstrate antimicrobial activity against the tested organisms. However, CuO NP2 and CuO NP3 demonstrated inhibitory effects on the growth of all tested organisms at 250 µg mL⁻¹, except <em>E. coli</em>, which was inhibited at 500 µg mL⁻¹. The antimicrobial activities of CuO NPs varied based on their copper content. Molecular docking studies were conducted to estimate the binding affinities of CuO NPs towards proteins that played a role in the virulence and antibiotic resistance of pathogens, which indicated a high affinity for PBP2a, Bam A and listeriolysin proteins. These results are encouraging for the design of CuO NPs containing biocides alone or in a composite form.</div></div>","PeriodicalId":101029,"journal":{"name":"Plant Nano Biology","volume":"11 ","pages":"Article 100128"},"PeriodicalIF":0.0,"publicationDate":"2025-02-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143143735","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This eco-friendly technique not only eliminates the need for hazardous chemicals but also capitalizes on the natural reducing and capping properties of biowaste.

The ultrasound-assisted synthesis provides a rapid, energy-efficient, and scalable process for nanocomposite fabrication, demonstrating excellent biocompatibility, uniformity, and stability. Furthermore, the approach not only offers a solution to the challenge of hazardous chemical use in nanoparticle (NPs) synthesis but also contributes to waste management by valorizing agricultural by-products.

These nanoparticles also influence the production of bacoside-A, a compound known for its memory-enhancing effects. This review focuses on the green synthesis of these metallic NPs using BM extracts, examining how nanoparticles stimulate the production of secondary metabolites, particularly bacoside-A. When exposed to nanoparticles, BM plants experience oxidative stress, which activates critical biosynthetic pathways such as the MEP (methylerythritol phosphate) and MVA (mevalonate) pathways, both of which are essential for the synthesis of bacoside-A and other terpenoids. Nanoparticles also enhance the activity of enzymes like DXS (1-Deoxy-d-xylulose 5-phosphate synthase) and HMGR (3-Hydroxy-3-methylglutaryl coenzyme A reductase), leading to the increased production of bioactive compounds. Additionally, the stress induced by nanoparticles elevates gene expression related to plant defense mechanisms, further boosting secondary metabolite synthesis. The review also highlights the potential therapeutic benefits of these nanoparticles, particularly in the fields of antimicrobial, anticancer, and neuroprotective treatments. Nanoparticles enhance the bioavailability and effectiveness of therapeutic agents, making them a valuable tool in biomedical applications.
