Influence of Luminescent Nanomaterials on Plant Growth and Development

Abstract As an emerging research hotspot in nanotechnology, luminescent nanomaterials (LNMs) have attracted much attention due to their unique properties. Meanwhile, their potential release into the environment has also been investigated by researchers. Plants, as an essential part of the ecosystem, are the starting point of bioaccumulation. Thus, to understand the interaction between LNMs and plants would be one of the critical aspects of risk assessment. Currently, there are still very few reports in this field, where a potential guidance is urgently necessary. Bearing this in mind, herein, based on our own research experience, we summarize the effects of four typical kinds of LNMs (quantum dots, carbon dots, upconversion nanoparticles, and metal nanoclusters) on plant growth and development, including the transport of materials in plants and their toxicity to plants, as well as the according experimental techniques. Finally, the current challenges and prospects are pointed out, thereby hoping to provide a timely fundamental guidance for future research.
