Patents by Inventor Todd J. Harris

Todd J. Harris has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Publication number: 20170087183
    Abstract: Embodiments of the present invention relate to methods for preparing high optical density solutions of nanoparticle, such as nanoplates, silver nanoplates or silver platelet nanoparticles, and to the solutions and substrates prepared by the methods. The process can include the addition of stabilizing agents (e.g., chemical or biological agents bound or otherwise linked to the nanoparticle surface) that stabilize the nanoparticle before, during, and/or after concentration, thereby allowing for the production of a stable, high optical density solution of silver nanoplates. The process can also include increasing the concentration of silver nanoplates within the solution, and thus increasing the solution optical density.

  • Publication number: 20160287741
    Abstract: Embodiments of the present invention relate to a metastable silver nanoparticle composite, a process for its manufacture, and its use as a source for silver ions and/or colorimetric signaling In various embodiments, the composite comprises, consists essentially of or consists of metastable silver nanoparticles that change shape when exposed to moisture, a stability modulant that controls the rate of the shape change, and a substrate to support the silver nanoparticles and the modulant.

  • Publication number: 20090246142
    Abstract: The present invention provides triggered self-assembly nanosystems. Such nanosystems comprise a population of triggered self-assembly conjugates, each conjugate comprising one or more monomeric units and one or more complementary binding moieties. In some embodiments, inventive nanosystems and conjugates can be used to treat and/or diagnose a disease, disorder, and/or condition.
