  • Publication number: 20230417677
    Abstract: A method for spatially locating a target inside a sample and providing spectral information for imaging the target includes illuminating a light source onto a sample to produce a backscattered optical signal; spectrally scanning and detecting the backscattered optical signal at selected spectral increments using a rapid wavelength-tuning solid-state device; providing three-dimensional spectral information (x, y, wavelength) from the sample at a series of wavelengths of interest; spatially scanning the backscattered signal in a two-dimensional plane at selected spatial increments; providing three-dimensional spatial information (x, y, z) from the sample at a series of spatial dimensions of interest; and combining the three-dimensional spectral information and the three-dimensional spatial information to produce a four-dimensional (x, y, z, and wavelength) data hypercube for use in collecting data from inside the sample.

  • Publication number: 20230201624
    Abstract: 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.

  • Patent number: 11324797
    Abstract: 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.

  • Patent number: 11260128
    Abstract: 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.

  • Patent number: 10876150
    Abstract: 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.

  • Patent number: 10835756
    Abstract: The present invention relates to methods for treating cell proliferation disorders comprising: (1) administering to the subject at least one activatable pharmaceutical agent that is capable of activation by a simultaneous two photon absorption event and of effecting a predetermined cellular change when activated; (2) administering at least one plasmonics-active agent to the subject, and (3) applying an initiation energy from an initiation energy source to the subject, wherein the plasmonics-active agent enhances or modifies the applied initiation energy, such that the enhanced or modified initiation energy activates the activatable pharmaceutical agent by the simultaneous two photon absorption event in situ, thus causing the predetermined cellular change to occur, wherein said predetermined cellular change treats the cell proliferation related disorder; and the use of plasmonics enhanced photospectral therapy (PEPST) and exiton-plasmon enhanced phototherapy (EPEP) in the treatment of various cell prolifer
