“…Nevertheless, Au-NPs have been found to possess positive effects on germination index in cucumber and lettuce [20]. Enhanced seed yield, seed germination rate, vegetative growth, and free radical scavenging activity in Arabidopsis thaliana exposed to Au-NPs have been also demonstrated [21]. Recent research has shown that Au-NP fertilizer can enhance the anti-inflammatory effects of red ginseng on mouse peritoneal macrophages [22].…”

(1) Background: Application of nanotechnology or nanomaterials in agricultural food crops has attracted increasing attention with regard to improving crop production, quality, and nutrient utilization. Gold nanoparticles (Au-NPs) have been reported to enhance seed yield, germination rate, and anti-oxidant potential in food crops, raising concerns about their toxicity potential. In this study, we evaluated the oral toxicity of red ginseng exposed to colloidal Au-NPs during cultivation (G-red ginseng) in rats and their intestinal transport mechanism. (2) Methods: 14-day repeated oral administration of G-red ginseng extract to rats was performed, and body weight, hematological, serum biochemical, and histopathological values were analyzed. An in vitro model of human intestinal follicle-associated epithelium (FAE) and an intestinal epithelial monolayer system were used for intestinal transport mechanistic study. (3) Results: No remarkable oral toxicity of G-red ginseng extract in rats was found, and Au-NPs did not accumulate in any organ, although Au-NP transfer to G-red ginseng and some increased saponin levels were confirmed. Au-NPs were transcytozed by microfold (M) cells, but not by a paracellular pathway in the intestinal epithelium. (4) Conclusion: These findings suggest great potential of Au-NPs for agricultural food crops at safe levels. Further study is required to elucidate the functional effects of Au-NPs on ginseng and long-term toxicity.

“…Seed or seedling treatment with Au NPs (62 µg mL −1 ) improved seed germination in Lactuca sativa and Cucumis sativus , Brassica juncea (10 ppm), and Gloriosa superba (1000 µ m ) . Au NP treatments also enhanced plant growth and yield, including the number, area, and chlorophyll and sugar content of leaves, and 10 and 80 µg mL −1 Au NPs promoted antioxidant production and seed germination in Arabidopsis thaliana . These positive effects, however, may be connected with stimulation of biochemical pathways as the response on the low doses of xenobiotics.…”

In this Review, an effort is made to discuss the most recent progress and future trend in the two‐way traffic of the interactions between plants and nanoparticles (NPs). One way is the use of plants to synthesize NPs in an environmentally benign manner with a focus on the mechanism and optimization of the synthesis. Another way is the effects of synthetic NPs on plant fate with a focus on the transport mechanisms of NPs within plants as well as NP‐mediated seed germination and plant development. When NPs are in soil, they can be adsorbed at the root surface, followed by their uptake and inter/intracellular movement in the plant tissues. NPs may also be taken up by foliage under aerial deposition, largely through stomata, trichomes, and cuticles, but the exact mode of NP entry into plants is not well documented. The NP–plant interactions may lead to inhibitory or stimulatory effects on seed germination and plant development, depending on NP compositions, concentrations, and plant species. In numerous cases, radiation‐absorbing efficiency, CO2 assimilation capacity, and delay of chloroplast aging have been reported in the plant response to NP treatments, although the mechanisms involved in these processes remain to be studied.

“…Another effort in the agro sector was put forward to induce the growth and yield enhancements of Arabidopsis thaliana by the exposure of gold nanoparticles. Gold nanoparticles can serve as promising tool to increase the seed yields of plants [3]. Currently, we are dealing with the isolation of cellulose nanocrystals from the leaves/biowastes of plants.…”

Nanotechnology is one of the most promising tools for the current revolution in agri-food sector. Nanotechnology approaches provide novel and innovative ways to improve crop yield and to reduce the use of harmful crop protection agents. Nanotechnology can be useful for biotic and abiotic stress tolerance of plants, lesser use of pesticides/insecticides/herbicides, nanosensors for crop protection from bacteria, disease treatment, pest control management and genetic manipulations by nano delivery vehicles. Also, nanotechnology has great advantages in food sector like detection of pesticides/toxicants in food items, development of food storage and packaging materials, enhancement of shelf life of foods, nanoencapsulation of food nutraceuticals or bioactive molecules, detection of pathogens in food materials, enhancement of food taste, color and odour. Above all, safety concerns regarding the use of nanomaterials should be of priority before their exploration for positive impact on agriculture and food.
