Efficient and Targeted Delivery of Agrochemicals to Phloem Using Nanomaterials

Prof. Juan Pablo Giraldo and his lab at the University of California, Riverside have developed a method for the targeted delivery of nanomaterials to the phloem such as pesticides, herbicides, and fertilizers using carbon dots with a sucrose-functionalized nanoparticle surface (sucQDs). This technology is advantageous surface functionalization with sucrose enables faster and more efficient foliar delivery of nanoparticles into the plant phloem, a vascular tissue responsible for long-distance transport of sugars from sources (i.e., mature leaves) to sinks (i.e., roots).

This technology is available for non-exclusive licensing.

Potential Applications

  • Nanomaterials for improving the delivery efficiency of agrochemicals to plant tissues and organs such as the phloem and roots.
  • Targeted delivery to reduce the loss of agrochemicals in soil.
  • A biorecognition delivery approach for targeting nanomaterials with cargoes to plant tissues and organs.
