摘要
铜基纳米颗粒是工业上较常制备及使用的纳米材料之一,具有比表面积大、活化能高、活性位点多等特点,因而具备广泛的应用前景。铜基纳米颗粒可以提高植物的营养吸收及生长参数,诱导植物产生系统抗性,因而可作为植物生长调节剂加以应用;同时铜基纳米颗粒对生物细胞也具备一定的生理毒性,可使细胞产生氧化应激反应,并可导致膜崩解,利用这一特性,还可将铜基纳米颗粒用作抑菌剂或除草剂。文章阐述了铜基纳米颗粒的促生长机制、其在生物细胞中造成的生理损害以及相关机理的研究进展,探讨了铜基纳米颗粒在农药领域作为植物生长调节剂、抑菌剂及除草剂应用的可能性,以期为新型农药的研发与生产提供新的思路。
Copper-based nanoparticles are one of the most frequently prepared and used nanomaterials in industry. They have the characteristics of large specific surface area, high activation energy and many active sites, which have wide application prospect. Copper-based nanoparticles can improve the nutritional absorption and growth parameters of plants, and induce systemic resistance. Therefore can be used as plant growth regulators. In addition, copper nanoparticles also have physiological toxicity,which can cause oxidative stress reaction and membrane disintegration in cells. This property can be used in the field of pesticide as antimicrobials or herbicide. This review summaried the research progress of the growth promoting mechanism of copper-based nanoparticles and the physiological damage in cells and their related mechanism. The potential application of copper-based nanoparticles as plant growth regulators, antimicrobials and herbicides in the field of pesticide was discussed. And this review has also provided new ideas for the research and production of new pesticides.
