  • Publication number: 20190373885
    Abstract: Quaternary ammonium materials may be immobilized onto a metal oxide nanoparticle to provide a fixed-quat nanoparticle material. A particular example uses a silicon alkoxide as a silicon source material to provide a fixed-quat SiNP/NG material composition through either acidic or basic hydrolysis of the silicon alkoxide material. Particular materials may be characterized spectroscopically to ensure that the desirable materials are properly bound. Specific applications of fixed-quat SiNP/NC material compositions in accordance with the embodiments include, but are not limited to agricultural biocide applications and tobacco smoke selective filtration applications.

  • Publication number: 20190082615
    Abstract: Described herein are devices, systems and methods for delivering therapeutic compositions to plants. Specifically exemplified herein is a device comprising a plurality of microneedles for creating pores in an effective area of a target plant and then applying a second device loaded with the therapeutic composition. The microneedle device is designed to impart pores that allow for access of the therapeutic composition to the plant vascular system including phloem.

  • Publication number: 20180295836
    Abstract: A nanoparticle for use within a composition for treating tomatoes as well as other agricultural products comprises: (1) a first shell layer comprising a leachant permeable base material in addition to a multi-valent metal (i.e., typically copper) material; and (2) a second shell layer comprising a Quat material. Due to the multi-valent metal material and the Quat, the nanoparticle and the composition provide superior performance when treating tomatoes.

  • Patent number: 10085444
    Abstract: A silica-based nanoformulation and method is used to treat citrus canker, inhibit the growth of mold and mildew, and add nutrients to soil used for agricultural purposes. The nanotechnology-enabled copper-loaded, silica nanoformulation (CuSiNP/NG) design is a “revolutionary re-invention” of Cu for safe application because it provides a formulation with maximum abundance of ionic Cu, provides sustained and optimal Cu ion release for long-term disease protection, better adherence to plant surfaces and structural surfaces due to gel-based nanostructure of CuSiNG, thus avoiding multiple spray applications and reducing the amount of Cu used in comparison to existing Cu compounds without compromising antibacterial activity.
