“…In agriculture, it is used to detect the soil conditions, a variety of pesticides, fertilizers, etc. In food packaging, it is used to identify the chemicals, pathogens, and toxins in food [94]. By observing the popularity of nanosensors in biomedical applications nowadays nanobiochar is also used in the synthesis of sensors for the detection of contaminants in the water [95].…”

Magnetic nanobiochar (MNBC) is a sort of nanobiochar that has been enhanced with magnetic qualities. MNBC is made from a variety of feedstocks, including wood chips, agricultural waste, municipal sludge, animal manure, and other organic waste. These feedstocks are pyrolyzed at various temperatures to produce biochar, which is then mixed with magnetic precursors to create MNBC. Crystallinity, high porosity, specific surface area, and great catalytic activity are a few of the dynamic properties of MNBC. The major purpose of this review paper is to characterize MNBC, using the various biochar synthesis methods and how bulk biochar is converted into MNBC with their high-value applications discussed here.

“…Additionally, hollow formations can protect against degradation processes and increase flexibility and elasticity in non-rigid structures, although they can also provide rigidity and compactness to solid structures. The diverse behavior of NPs also makes them viable for developing nanopesticides, nanoherbicides, and nanosensors for plant, soil, and pest monitoring in an intelligently controlled environment, a trend in agriculture 4.0 ( Kah et al., 2019 ; Rastogi et al., 2019 ; Shawon et al., 2020 ). However, some of the mentioned physical and chemical characteristics are also related to phytotoxicity, potential environmental toxicity, and human health hazards ( Paramo et al., 2020 ; Ayub et al., 2022 ), which involves mandatory experimentation to find the appropriate doses, exposure times, and types of NP types for every crop.…”

The efficient use of natural resources without negative repercussions to the environment has encouraged the incursion of nanotechnology to provide viable alternatives in diverse areas, including crop management. Agriculture faces challenges due to the combination of different abiotic stresses where nanotechnology can contribute with promising applications. In this context, several studies report that the application of nanoparticles and nanomaterials positively affects crop productivity through different strategies such as green synthesis of nanoparticles, plant targeted protection through the application of nanoherbicides and nanofungicides, precise and constant supply of nutrients through nanofertilizers, and tolerance to abiotic stress (e.g., low or high temperatures, drought, salinity, low or high light intensities, UV-B, metals in soil) by several mechanisms such as activation of the antioxidant enzyme system that alleviates oxidative stress. Thus, the present review focuses on the benefits of NPs against these type of stress and their possible action mechanisms derived from the interaction between nanoparticles and plants, and their potential application for improving agricultural practices.

“…The properties at the nano-scale of NPs result on a more organised and efficient material (enhanced optical and mechanical properties, and high chemical customisation among others) in comparison with conventional biosensors. Nanobiosensors can play a crucial role in agriculture by detecting and monitoring various parameters related to plant health and environmental conditions [ 5 , 6 ]. These small devices can detect the presence of pathogens, pests, and diseases at an early stage, allowing for timely intervention and minimising crop losses [ 7 ].…”

In the current scenario of climate change, global agricultural systems are facing remarkable challenges in order to increase production, while reducing the negative environmental impact. Nano-enabled technologies have the potential to revolutionise farming practices by increasing the efficiency of inputs and minimising losses, as well as contributing to sustainable agriculture. Two promising applications of nanotechnology in agriculture are nanobiosensors and nanoformulations (NFs). Nanobiosensors can help detect biotic and abiotic stresses in plants before they affect plant production, while NFs can make agrochemicals, more efficient and less polluting. NFs are becoming new-age materials with a wide variety of nanoparticle-based formulations such as fertilisers, herbicides, insecticides, and fungicides. They facilitate the site-targeted controlled delivery of agrochemicals enhancing their efficiency and reducing dosages. Smart farming aims to monitor and detect parameters related to plant health and environmental conditions in order to help sustainable agriculture. Nanobiosensors can provide real-time analytical data, including detection of nutrient levels, metabolites, pesticides, presence of pathogens, soil moisture, and temperature, aiding in precision farming practices, and optimising resource usage. In this review, we summarise recent innovative uses of NFs and nanobiosensors in agriculture that may boost crop protection and production, as well as reducing the negative environmental impact of agricultural activities. However, successful implementation of these smart technologies would require two special considerations: (i) educating farmers about appropriate use of nanotechnology, (ii) conducting field trials to ensure effectiveness under real conditions.
