Patent number: 10493296Abstract: Products, compositions, systems, and methods for modifying a target structure which mediates or is associated with a biological activity, including treatment of conditions, disorders, or diseases mediated by or associated with a target structure, such as a virus, cell, subcellular structure or extracellular structure. The methods may be performed in situ in a non-invasive manner by placing a nanoparticle having a metallic shell on at least a fraction of a surface in a vicinity of a target structure in a subject and applying an initiation energy to a subject thus producing an effect on or change to the target structure directly or via a modulation agent. The nanoparticle is configured, upon exposure to a first wavelength ?1, to generate a second wavelength ?2 of radiation having a higher energy than the first wavelength ?1.Type: GrantFiled: February 17, 2016Date of Patent: December 3, 2019Assignees: IMMUNOLIGHT, LLC, DUKE UNIVERSITYInventors: Tuan Vo-Dinh, Jonathan P.

Publication number: 20180230523Abstract: Gold nanorattle probes are provided that are highly tunable, physiologically stable, and ultra-bright Raman probes for in vitro and in vivo surface-enhanced Raman scattering (SERS) applications. The nanorattles contain an essentially uniform gap between core and shell that is tunable and can range from 2nm to 10nm in width. This provides numerous advantages including allowing for increased loading with a variety of dye molecules that exhibit SERS in various spectral regions, including the “tissue optical window” for in vivo studies. In addition, the nanorattle probes provide an internal label when used in diagnostic methods to detect nucleic acids, proteins and other biotargets. The nanorattles have an essentially spherical gold metal nanoparticle core, a porous material of silver metal of an essentially uniform width surrounding the nanoparticle core that is loaded with one or more SERS reporter molecules, and an outer gold metal shell encapsulating the porous material.Type: ApplicationFiled: January 29, 2018Publication date: August 16, 2018Inventors: Tuan Vo-Dinh, Naveen Gandra, Hoan T.

Publication number: 20180133319Abstract: The presently disclosed subject matter is directed to a method of treating cancer, such as (but not limited to) metastatic bladder and breast cancer. The disclosed method comprises using two treatment modalities to synergistically treat primary and secondary tumor cells in a subject. The first element of the method comprises administering a therapeutically effective amount of a plasmonics-active metal nanoparticle to a subject comprising a primary cancer and a distant metastatic site, wherein the nanoparticle concentrates at the primary cancer. The method further comprises exposing the subject to photon radiation at the site of the primary cancer. The second element of the disclosed method comprises administering a therapeutically effective amount of an immune checkpoint modulator to the subject. The synergistic combination provides a rapid, safe, and effective treatment of local and distant lesions, better than each modality alone.Type: ApplicationFiled: December 22, 2017Publication date: May 17, 2018Inventors: Tuan Vo-Dinh, Brant A.
