Humans rely on four primary sources for food consumption: agriculture, aquaculture, poultry, and livestock. Nanotechnology, owing to its unique advantages, has brought about a breakthrough in the mentioned sources to address food security issues. In this study, the application of nanotechnology in agriculture, aquaculture, poultry, and livestock has been elaborately discussed. In agriculture, nanofertilizers, nanopesticides, and nanopriming have contributed significantly to improving crop production. Likewise, practices in aquaculture have been greatly eased by the introduction of nano-enhanced feed, nanovaccines, and nanofiltration. In poultry, essential aspects such as supplementing appropriate nutrients in specific quantities and disease prevention have become more manageable thanks to nanotechnology. In a similar manner, nanotechnology has led to colossal improvements in disease prevention, animal reproduction, and drug delivery in livestock. However, despite all these prospects, some challenges remain for the implementation of nanotechnology in the food production sector. The regulatory frameworks for the implementation of nanotechnology remain underdeveloped, consumer acceptance is a significant issue, and the environmental fate and ecotoxicity of nanotechnology remain uncertain. This comprehensive review article aims to provide in-depth insights into the current status, challenges, and prospects of nanotechnology in primary food sources, with the ultimate goal of addressing worldwide food scarcity.</div></div>","PeriodicalId":101029,"journal":{"name":"Plant Nano Biology","volume":"14 ","pages":"Article 100208"},"PeriodicalIF":7.7,"publicationDate":"2025-10-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145270375","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}

However, their ecological safety and biosafety need to be assessed for responsible use and disposal, considering various environmental factors. This study investigates the phytotoxicity of magnesium oxide nanoparticles synthesised using butterfly pea flower (<em>Clitoria ternatea</em>) extract through a modified co-precipitation method. The synthesis was confirmed by UV–visible spectroscopy with a distinct absorbance peak at 340 nm. Morphological analysis through scanning electron microscopy (SEM) revealed agglomerated, porous nanoparticles, while X-ray diffraction (XRD) confirmed their crystalline nature with an average size of 33.56 nm. Fourier transform infrared spectroscopy (FTIR) revealed characteristic MgO bonding and hydroxyl group presence, indicating the nanoparticles’ high chemical reactivity. Ecotoxicity assessments by phytotoxicity studies demonstrated no distinct effects on Vigna mungo seedlings' physiology. Moreover, MgO NPs positively influenced soil health by increasing the concentration of essential nutrients (N, P, K) without altering pH or electrical conductivity. Rhizosphere microflora analysis showed increased bacterial colony formation, improving soil microbial activity. Endophytic microflora in plant tissues also exhibited higher bacterial colony growth. These findings confirm that the fabricated nanoparticles are biocompatible and environmentally safe, making them a promising material for diverse applications with minimal ecological impact. This study employs CB-Dock molecular docking to evaluate MgO interactions with plant growth-related proteins (7JRG, 7JRO, 2CV6). Favourable interaction and cavity detection scores suggest potential surface-level interactions.

Exogenous dsRNA-mediated RNA interference (RNAi) is a promising gene silencing approach to combat viral pathogens or suppress specific plant endogenous genes without transgenic modification. The effective implementation of RNAi depends on the interactions of NPs with plants, including particle size and charge, uptake, translocation, physical barriers, and physiological and environmental conditions. The difficulties in achieving silencing phenotypes in field conditions remain a barrier to widespread agricultural adoption. Despite advancements, gaps remain in understanding NP uptake mechanisms and transport. Recently, clathrin-mediated endocytosis was found to be a driver of RNA root uptake, which we are also able to confirm with experimental observations. This study focuses on the role of root hairs as key mediators of dsRNA nanoparticle uptake. Inhibition of root hairs reduces RNA uptake, while increased root hair density enhances uptake. Lateral roots can bypass the casparian strip, and higher root hair density leads to increased RNA internalization beyond this barrier. We also propose that caveolar-mediated endocytosis can play a role in cationic polymer complexed-dsRNA NP uptake, and that the integration of RNA into cell walls across the plant allows for a slow release into the cell and sustained silencing phenotype. Validation of the microscopy results was performed by targeting phytoene desaturase (PDS) with dsRNA NPs by irrigation, where bleaching was achieved.

Green synthesis using honey offers an eco-friendly, straightforward approach, with glucose and fructose in honey playing key roles in AgNPs synthesis. This study explores the effects of glucose and fructose concentrations in various honey types on AgNPs formation at 27–30 °C and pH 6–6.5, complemented by molecular docking studies. The sugar content in different honey samples was as follows: Cottonwood (56.66 %), Rambutan (49.95 %), Rubber (44.54 %), and Coffee (37.56 %). Higher bioreductor concentrations led to increased absorbance in the UV-Vis spectra; however, antibacterial activity decreased, albeit not significantly. This can be attributed to lower reducing sugar concentrations, which resulted in smaller AgNPs with a larger surface area, consequently affecting their antibacterial efficacy. The synthesized AgNPs were spherical (8–10 nm) and exhibited face-centered cubic crystallinity. The inhibition zones for AgNPs derived from cottonwood, rambutan, rubber, and coffee honey against <em>Staphylococcus aureus</em> were 14.51 mm, 14.54 mm, 15.45 mm, and 16.04 mm, respectively, and against <em>Pseudomonas aeruginosa</em> were 15.10 mm, 15.70 mm, 15.81 mm, and 15.90 mm, respectively. The microdilution broth assay revealed a sharp increase in antibacterial inhibition within the AgNPs concentration range of 5–50 ppm, plateauing above 50 ppm, with the steep increase halting between 20 and 40 ppm.
