Potential applications of copper-based nanoparticles in pesticide

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.
