Interactions of Metal‐Based Engineered Nanoparticles with Plants: An Overview of the State of Current Knowledge, Research Progress, and Prospects

Nanotechnology is a potential technique for increasing agricultural output by producing nano-fertilizers, improving herbicide and pesticide efficacy, regulating soil fertility, managing wastewater, and detecting illnesses. It is also virtuous for industrial food processing since it boosts market value, improves nutritional and sensory properties, enhances safety, and boosts antibacterial protection. Moreover, nanotechnology may also assist farmers in reducing post-harvest losses by prolonging shelf life via the use of nanoparticles. Furthermore, nanoscience develops new ideas that lead to a better understanding of nanoparticles and their mechanisms of action in plants. Plants can grow and develop more effectively when the physiological-biochemical and molecular pathways involving nanoparticles in plants are understood. Scientists have developed a broad range of nanoparticles (NPs) such as Au, Ag, Pt, Fe, Cu, Cd, ZnO, and TiO2. At the same time, nanoscience gives us new ideas and diverts our intentions to attain some suitable mechanism mode for the functions of NPs in plants. The proper functionality of the physical, biological, and cellular mechanisms of NPs requires selected plant species to influence the variation in the different phases of plant growth and development. Although several reviews on engineered nanoparticles have been published in recent years, few have focused on their current applications, transport, interaction, and physio-chemical aspects of metal-based nanoparticles (MBNPs) and carbon-based nanoparticles (CBNPs) with crops. As a result, we evaluated the behaviors of (MBNPs) and (CBNPs) in agricultural systems, including absorption and translocation of MBNPs and CBNPs in crop plants, physiological and biochemical effects of MBNPs on plants, and factors influencing MBNPs and CBNPs' interactions on plants. This review will help glow nanotechnology by promoting scientific study on MBNPs and metal oxides nanoparticles MONPs and understanding the risks and advantages of their association with plants.
