“…According to the authors, the positive effects were primarily attributed to better water absorption and retention by the plant (Tripathi et al, 2011). Furthermore, in a typical study carried out by Tripathi and Sarkar (2015), water soluble carbon nano-dots (wsCND), upon exposure to wheat plants under dark and light conditions, proved to enhance the growth of roots and shoots.…”

The expansion of nanotechnology and its ubiquitous applications has fostered unavoidable interaction between engineered nanomaterials (ENMs) and plants. Recent research has shown ambiguous results with regard to the impact of ENMs in plants. On one hand, there are reports that show hazardous effects, while on the other hand, some reports highlight positive effects. This uncertainty whether the ENMs are primarily hazardous or whether they have a potential for propitious impact on plants, has raised questions in the scientific community. In this review, we tried to demystify this ambiguity by citing various exposure studies of different ENMs (nano-Ag, nano-Au, nano-Si, nano-CeO2, nano-TiO2, nano-CuO, nano-ZnO, and CNTs, among others) and their effects on various groups of plant families. After scrutinizing the most recent literature, it seems that the divergence in the research results may be possibly attributed to multiple factors such as ENM properties, plant species, soil dynamics, and soil microbial community. The analysis of the literature also suggests that there is a knowledge gap on the effects of ENMs towards changes in color, texture, shape, and nutritional aspects on ENM exposed plants.

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.

“…Numerous nanomaterials, including carbon materials, have been effectively utilized for seed germination of various plant sources . Owing to their superior physiochemical properties, CDs have also been demonstrated as an active ingredient for seed germination/plant growth studies . The use of non‐renewable source‐derived CDs for seed germination may be limited because of their possible toxicity levels.…”

BACKGROUND Bio‐oils can be effectively used for the preparation of bio‐based materials owing to their chemical compositions. In this study, brown macroalgal‐derived bio‐oil was used for the synthesis of graphene oxide‐carbon dot composite by a simple hydrothermal process. RESULTS A simple and facile hydrothermal process was explored for the preparation of green‐emitting graphene oxide‐carbon dot (GO‐CD) composite from brown macroalgal biomass‐derived bio‐oil as carbon source in water medium at 170 °C for 4 h. An aqueous solution of the prepared GO‐CD composite exhibited green emission under ultraviolet (UV) radiation exposure. Raman spectroscopy and transmission electron microscopy analyses confirmed the successful formation of GO‐CD composite. Physicochemical characterizations such as phase structure and optical properties of the GO‐CD were investigated by X‐ray diffraction, UV–visible and photoluminescence analyses. The effects of the GO‐CD composite on the seed germination of mung bean were studied. It was found that, compared with the control (100/0 vol% water; total length of plant ∼20 cm), the 75/25 vol% water/GO‐CD ratio treatment resulted in better plant growth (total length of plant ∼25 cm) under the studied conditions. Further increase in GO‐CD concentration above the optimum level resulted in a decrease in plant growth but did not have a significant effect on the mass, root and leaf mass development. CONCLUSION Brown macroalgal bio‐oil‐derived graphene oxide‐carbon dot composite were explored for the seed germination of mung bean and the results showed that a low concentration enhanced the plant growth. © 2019 Society of Chemical Industry
