In this study, we present a bio-inspired method for the synthesis of CeO₂-TiO₂ nanocomposites (NCs) using phytochemicals extracted from the outer calyx leaves of <em>Physalis peruviana</em> fruits, under ultrasound sonication. 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 synthesized NCs were thoroughly characterized using fourier-transform infrared spectroscopy (FTIR), UV-Vis spectroscopy, transmission electron microscopy (TEM), scanning electron microscopy (SEM), energy-dispersive X-ray spectroscopy (EDX), X-ray diffraction (XRD), and thermogravimetric analysis (TGA). Their antibacterial activity was evaluated against various Gram-positive and Gram-negative bacteria, and their antioxidant potential was also assessed. This work highlights the remarkable role of phytochemicals from fruit calyx leaves as bio-templates, facilitating the sustainable production of CeO₂-TiO₂ NCs. 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. Our findings underscore the promising applications of green-synthesized CeO₂-TiO₂ NCs in the biomedical and pharmaceutical industries, paving the way for future advancements in eco-friendly nanotechnology.</div></div>","PeriodicalId":101029,"journal":{"name":"Plant Nano Biology","volume":"11 ","pages":"Article 100130"},"PeriodicalIF":0.0,"publicationDate":"2025-02-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143143736","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}

Botanical insecticides offer an eco-friendly pest management strategy to combat this serious issue. <em>Piper aduncum</em> (<em>P. aduncum</em>) provides an available source of essential oil with significant plant protection effects, including biological activity against fall armyworm.

The findings showed that the two insects that were tested, <em>Pygomorpha vignaudii</em> and <em>Phyllotreta striolata</em>, were killed by crude extracts of <em>P. alliacea</em> and AgNPs. However, the insecticidal effect of Pa-AgNPs against <em>P. vignaudii</em> was more pronounced than the crude <em>P. alliacea</em> extracts.

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.
