“…TiO 2 -NPs are successful in reducing Cd absorption in several plants, including Coriandrum sativum [ 15 ], bamboo [ 87 ], rice [ 88 ], and summer savory [ 89 ]. The use of CaO-NPs in barley led to a notable reduction in shoot Cd (43–70%) and root (30–40%) of both genotypes [ 11 ]. CuONP treatment has also been demonstrated to decrease Cd levels in wheat, rice, and barley plants, concurrent with the plants’ enhanced growth under Cd treatment [ 90 , 91 ].…”

“…Recently, many techniques have been relied on to synthesize metallic NPs, such as chemical (co-precipitation, micro-emulsion, sol-gel, hydrothermal), physical (ion sputtering scattering, gamma radiations, electro-explosion, ion sputtering, pulse laser ablation, mechanical/ball milling), and biological (green synthesis with microorganisms and plant extracts) approaches [ 7 ]. According to the latest research, the external application of NPs can enhance the adaptation of plants to HMs by adjusting morpho-physiological and molecular mechanisms [ 8 – 11 ]. Hence, in sustainable agriculture, using NPs to stimulate plant adaptation to HM toxicity can be regarded as a reliable, ecologically safe, and long-term effective method, in contrast to conventional methodologies.…”

The primary factors that restrict agricultural productivity and jeopardize human and food safety are heavy metals (HMs), including arsenic, cadmium, lead, and aluminum, which adversely impact crop yields and quality. Plants, in their adaptability, proactively engage in a multitude of intricate processes to counteract the impacts of HM toxicity. These processes orchestrate profound transformations at biomolecular levels, showing the plant’s ability to adapt and thrive in adversity. In the past few decades, HM stress tolerance in crops has been successfully addressed through a combination of traditional breeding techniques, cutting-edge genetic engineering methods, and the strategic implementation of marker-dependent breeding approaches. Given the remarkable progress achieved in this domain, it has become imperative to adopt integrated methods that mitigate potential risks and impacts arising from environmental contamination on yields, which is crucial as we endeavor to forge ahead with the establishment of enduring agricultural systems. In this manner, nanotechnology has emerged as a viable field in agricultural sciences. The potential applications are extensive, encompassing the regulation of environmental stressors like toxic metals, improving the efficiency of nutrient consumption and alleviating climate change effects. Integrating nanotechnology and nanomaterials in agrochemicals has successfully mitigated the drawbacks associated with traditional agrochemicals, including challenges like organic solvent pollution, susceptibility to photolysis, and restricted bioavailability. Numerous studies clearly show the immense potential of nanomaterials and nanofertilizers in tackling the acute crisis of HM toxicity in crop production. This review seeks to delve into using NPs as agrochemicals to effectively mitigate HM toxicity and enhance crop resilience, thereby fostering an environmentally friendly and economically viable approach toward sustainable agricultural advancement in the foreseeable future.

The application of nanotechnology in phytoremediation of heavy-metal-polluted soil has revitalized this traditional remediation technology with higher efficiencies. Among various material types, micronutrient-based nanomaterials have recently come into the public spotlight because of their positive effects on plant performances without significant perturbation to the environmental media, while their effects and the related mechanisms to enhance the phytoremediation efficiencies remain largely uncovered. In this study, molybdenum trioxide nanoparticles (MoO 3 NPs) and molybdate (Mo 6+ ) were applied in combined heavy-metal-contaminated soils to explore their effects on plant tolerance and phytoextraction ability of a typical Cd hyperaccumulator, Solanum nigrum L. Experimental results indicated that low-level Mo (4 mg kg −1 ) application, especially for MoO 3 NPs, significantly improved the plant performance and Cd accumulation of S. nigrum by activating nutrient assimilation and antioxidative levels, while excessive Mo addition (20 and 40 mg kg −1 ) further exacerbated detrimental effects on plants under combined heavy-metal pressure. Furthermore, nontargeted metabolomic analysis was adopted to uncover the regulating mechanisms of Mo materials on plant responses. Under 4 mg kg −1 treatment, MoO 3 NPs stimulated metabolite expression related to carbohydrate biosynthesis and antioxidative systems to enhance plant tolerance and phytoextraction ability, revealing less metabolic perturbation compared to Mo 6+ treatment. Abscisic acid signaling was considered to be a key regulator contributing to differential regulating pathways between low-level Mo 6+ and MoO 3 NPs treatments. However, under higher Mo levels, both materials led to similar dysregulations in several important pathways concerning amino acid, lipid, and carbohydrate metabolisms. This study provided a theoretical basis for utilizing essential micronutrient-based nanomaterials to facilitate phytoremediation by hyperaccumulators during in situ remediation of heavy metals.

“…The maximum Cd limit in drinking water stipulated by the US EPA is 0.005 mg/L . Once the toxic Cd ions enter edible crops via the water/soil in which the crops grow, oxidative stress (overproduction of reactive oxygen species (ROS) with H 2 O 2 being the most abundant member of ROS) will be induced in the crops. , ROS are well recognized for playing a dual role as both beneficial and detrimental species depending on the ROS level (concentration) in plants; − when the level of ROS exceeds the basal (normal) level (H 2 O 2 at about 30 nmol·g –1 ), oxidative stress occurs. Cd ions inside plants deplete glutathione and protein-bound thiol groups and thus result in the overproduction of ROS (H 2 O 2 is the most abundant ROS member). , Thus, ROS in particular hydrogen peroxide in vivo inside the plants can be used as a biomarker of oxidative stress in edible crops induced by Cd ions.…”

Water-Dispersible Activatable Nanoprobe for Detecting Cadmium-Ion-Induced Oxidative Stress in Edible Crops via Near-Infrared Second-Window Fluorescence Imaging

Edible crops are important in terms of food security and sustainable agriculture. Heavy-metal-ion contamination of water/soil has deleterious impacts on the growth of edible crops. Among the heavy metals, cadmium (Cd) is toxic to plants, people, and animals, as it is widely used in industry; it has become the most important metal ion in the soil/water pollution. Once the toxic Cd ion enters edible crops via the water/soil in which the crops grow, it will induce oxidative stress (overproduction of reactive oxygen species with H2O2 being the most abundant) in the crops, and strong oxidative stress leads to the crops’ growth depression or inhibition. Hence, it is of great significance to accurately monitor the oxidative stress induced by Cd ions in edible crops, as the monitoring results could be employed for the early warning of Cd-ion pollution in water/soil. Herein, we design an activatable nanoprobe that can detect Cd-ion-induced oxidative stress in edible crops via near-infrared second-window (NIR-II) fluorescence imaging. The molecular probe IXD-B contains the diphenylamine-modified xanthene group acting as the electron-donating unit, bis(methylenemalononitrile)indan as the electron-accepting unit, and the methenephenylboronic acid group as the recognition moiety for H2O2 and the fluorescence quencher. The probe molecules being encapsulated by the amphiphilic DSPE-PEG2000 render the water-dispersible nanoprobe (IXD-B@DSPE-PEG2000). When the nanoprobe enters the edible crops, it can be activated by the overexpressed H2O2 therein and consequently emit strong NIR-II fluorescence signals for visualizing and tracking the oxidative stress in edible crops induced by Cd ions.
