  • Compositions comprising a nanoparticle, a molecular basket comprising cyclodextrin, and a chloroplast-targeting peptide and methods of use thereof
    Patent number: 11186845
    Abstract: Compositions for chemical and/or genetic modification of chloroplasts of plants include a functionalized nanoparticle composition linked to a chloroplast-targeting peptide and a functionalized single walled carbon nanotube (SWNT) composition complexed with a nucleic acid cassette encoding a plastid-specific ribosomal RNA operon (prrn). Methods for chemically and/or genetically modifying chloroplasts of plants include administering these chloroplast-targeted compositions to the leaves of live plants.

  • Nanoceria augmentation of plant photosynthesis under abiotic stress
    Patent number: 10798938
    Abstract: A nanobionic approach for augmenting plant photoprotection and photosynthetic light energy conversion and carbon assimilation under abiotic (e.g., light) stress was used. Cerium oxide nanoparticles (nanoceria) improve Arabidopsis maximum quantum yield of photosystem II (10%) and carbon assimilation (19%) by protecting leaf mesophyll chloroplasts from damaging reactive oxygen species (ROS). Nanoceria augments scavenging of superoxide and hydroxyl radicals. For the latter, there are not known scavenging enzymatic pathways.
