Patent number: 11324797Abstract: Plasmonics-active metal nanostars are provided that can be used for treating and detecting cells in a subject. The modes of treatment include a photo-activated drug, which is activated by the photo-response of the nanostar to electromagnetic stimulation; a thermally-activated drug, which is activated by a thermal response of the nanostar to electromagnetic stimulation; and the thermal response of the nanostar itself to electromagnetic stimulation, which may directly or indirectly cause the death of an undesirable cell. Uptake of nanostars by undesirable cells may also aid in detection, by enhancing contrast or otherwise transforming electromagnetic stimulation during imaging.Type: GrantFiled: October 17, 2017Date of Patent: May 10, 2022Assignee: DUKE UNIVERSITYInventors: Tuan Vo-Dinh, Hsiangkuo Yuan, Andrew Fales

Patent number: 11260128Abstract: 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: GrantFiled: December 22, 2017Date of Patent: March 1, 2022Assignee: Duke UniversityInventors: Tuan Vo-Dinh, Brant A.

Patent number: 10876150Abstract: 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 2 nm to 10 nm 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: GrantFiled: January 29, 2018Date of Patent: December 29, 2020Assignee: Duke UniversityInventors: Tuan Vo-Dinh, Naveen Gandra, Hoan T.
