“…Various nanoscale materials/sensors, including metal-organic frameworks (MOFs), graphene oxide (GO), CNTs, molecularly imprinted polymers (MIP), nanozymes, and nanosensors, have been cooperatively used to detect, remediate, and extract unwanted compounds from food sources [ 120 ]. These nanoscale materials have also been used as components in devices tailored to the detection of chemical and biological contaminants, allowing the removal from the supply chain of toxic compounds, hence minimizing the distribution of contaminated products to the consumer [ 121 ].…”

Intensive conventional agriculture and climate change have induced severe ecological damages and threatened global food security, claiming a reorientation of agricultural management and public policies towards a more sustainable development model. In this context, nanomaterials promise to support this transition by promoting mitigation, enhancing productivity, and reducing contamination. This review gathers recent research innovations on smart nanoformulations and delivery systems improving crop protection and plant nutrition, nanoremediation strategies for contaminated soils, nanosensors for plant health and food quality and safety monitoring, and nanomaterials as smart food-packaging. It also highlights the impact of engineered nanomaterials on soil microbial communities, and potential environmental risks, along with future research directions. Although large-scale production and in-field testing of nano-agrochemicals are still ongoing, the collected information indicates improvements in uptake, use efficiency, targeted delivery of the active ingredients, and reduction of leaching and pollution. Nanoremediation seems to have a low negative impact on microbial communities while promoting biodiversity. Nanosensors enable high-resolution crop monitoring and sustainable management of the resources, while nano-packaging confers catalytic, antimicrobial, and barrier properties, preserving food safety and preventing food waste. Though, the application of nanomaterials to the agri-food sector requires a specific risk assessment supporting proper regulations and public acceptance.

“…Very recently, two-dimensional nanomaterials, such as graphene oxide (GO), titanium carbide, black phosphorus, and molybdenum disulde, have been used as excellent carriers for the construction of ultrasensitive biosensors due to their massive surface areas, exibility, superior stability, and abundant surface groups. [31][32][33] Our previous works also demonstrated the combination of monolayer GO and other nanoparticles (e.g., QDs, AuNPs, and AgNPs) as high-performance lm-like nanotags for LFIA methods. [34][35][36] For example, the GO nanosheet loaded one layer of dense QDs can act as exible uorescent tags for simultaneous detection of two kinds respiratory pathogens in real respiratory tract samples via LFIA strip.…”
