Abstract
Nano-agriculture is a fast-growing interdisciplinary field advancing from lab research to practical field application to tackle global food security and agri-environmental challenges. This concise review summarizes the agronomic functions and underlying molecular mechanisms of typical nanoparticles, including metal oxides (ZnO, TiO2), carbon-based, silica, and elemental (Ag, Se, Cu) nanomaterials, which contribute to crop nutrient regulation, growth improvement, stress tolerance, disease suppression and targeted delivery of bioactive ingredients. The literature synthesis is based on peer-reviewed articles retrieved from Web of Science and Scopus (2015–2026) using keywords combining nanoparticle types with agricultural applications. We further evaluate their potential hazards regarding soil ecosystem deterioration, crop phytotoxicity and food-chain safety. Three key future research directions are outlined: developing stimuli-responsive smart agrochemical nanocarriers, combining nanobiosensing with artificial intelligence for real-time crop monitoring, and optimizing eco-friendly green synthesis of nanomaterials. Overall, this review provides a roadmap enabling nano-agriculture to evolve from discrete single-purpose nanoparticle usage toward integrated precise, intelligent and environmentally sustainable agro-nanosystems.
ABSTRACT Climate change, soil degradation, resource depletion, and excessive agrochemical use necessitate sustainable agricultural innovations. Nanobiotechnology has emerged as a transformative approach to enhance crop productivity, resource-use efficiency, and environmental sustainability. Over the past 15 years, extensive research has explored nanoparticle (NP) mediated approaches for improving plant growth and resilience. This review provides a comprehensive account of emerging nano-enabled technologies, including nanoregulators, nanofertilizers, nanopesticides, nanobiosensors (detection sensitivity nM to pM levels), and nanocarrier-assisted genome editing platforms. Beyond summarizing recent advances, the review critically examines the mechanistic basis of NP-mediated improvements in nutrient uptake (20–60%), seed germination, abiotic stress tolerance, disease management, pesticide resistance mitigation, genetic transformation, and tissue culture. The review identifies that nanoparticle efficacy is highly dose-dependent, with most laboratory studies reporting optimal plant responses at 10–50 mg L−1, highlighting the need for standardized field-scale dose optimization. The review also critically discusses nanotoxicological concerns, biosafety, regulatory frameworks, commercialization pathways highlighting the transition of nanobiotechnology from laboratory research toward practical agriculture. Model-based analysis suggests that high-efficiency nano-fertilizers (γ≈ 6) can achieve yields comparable to those obtained with 200 kg ha−1 of conventional fertilizer using only ~40 kg ha−1 of nano-fertilizer. The review further evaluates the commercialization status of nano-enabled agricultural products, highlighting the successful market deployment of formulations such as Nano Urea, Nano DAP, Nano Zinc, nanopesticides, nano seed coatings, and nanobiosensors. Finally, key scientific, regulatory, economic, and societal challenges are identified, and future priorities are proposed to facilitate the safe, scalable, and responsible deployment of nanobiotechnology for sustainable and climate-resilient agriculture. GRAPHICAL ABSTRACTThe graphical abstract illustrates the diverse applications of nanobiotechnology in sustainable agriculture. It highlights the use of engineered nanoparticles and nanomaterials in precision nutrient delivery (nanofertilizers), targeted pest and disease management (nanopesticides), enhanced crop protection, stress tolerance, nanosensors for real-time monitoring of soil and plant health, and nano-enabled genetic engineering. These nanobiotechnological interventions improve nutrient use efficiency, increase crop productivity, reduce environmental pollution, and support climate-resilient, resource-efficient agricultural practices, thereby contributing to global food security and sustainable farming.Nanobiotech in Agriculture: Abiotic stress tolerance, essential nutrient uptake, disease control, genetic engineering and nanobiosensing.

The increase in global population and subsequent demand for food have led to intensive use of agrochemicals in agriculture to maximize productivity, triggering serious environmental consequences. In response to these challenges, organic farming is a viable alternative based on methods that promote natural resource conservation. However, a major challenge to its use is lower yields, limiting large-scale adoption. In this context, nanotechnology is an innovative tool capable of enhancing organic agricultural production through naturally derived nanomaterials such as nanofertilizers, nanopesticides, and soil amendments. The following review aims to analyze these naturally derived nanomaterials and assess their capacity to increase crop yields. This will determine whether these innovations can enable organic agriculture to achieve higher production levels. Additionally, there is the presentation of examples of commercially available naturally derived nanomaterials. This is followed by an examination of safety studies showing a variety of toxicological and ecotoxicological effects. Finally, an examination of regulatory frameworks related to nanomaterials reveals a lack of standardized regulations and permissions, creating uncertainty and delays in adopting new nanotechnologies in the organic agricultural sector. Naturally derived nanomaterials have the potential to enhance productivity indicators. However, it is crucial to promote international standards for regulatory permissions. It is only then that progress can be made toward the use of nanotechnology for a more efficient, ecological, and sustainable agriculture for the future.
