  • Publication number: 20180125432
    Abstract: Differences of electromagnetic (EM) properties between healthy and cancerous tissues allow detection of abnormal conditions occurring in a tissue of an animal, for example, intra-operative cancer detection. By using a time-varying EM field, electrical eddy currents are generated in the tissue sample, and assessed using phase-sensitive detection. In some aspects, a change in phase shift between the voltage in a receiver coil and the voltage in a driver coil provide a direct and immediate indication of differences in EM properties of specimens.

  • Patent number: 9587071
    Abstract: The present invention relates to methods, compositions, and kits for generating conjugated gold nanoparticles. In certain embodiments, the present invention provides methods of generating unsaturated conjugated gold nanoparticles by mixing naked gold nanoparticles with a first type of attachment molecules at a molar ratio such that the attachment molecules attach to the naked gold particles at a density level below the saturation level of the naked gold particles (e.g., at a saturation level of 1-99%). In some embodiments, a second type of attachment molecules (e.g., with the opposite charge as the first type of attachment molecules) are mixed with the unsaturated conjugated gold nanoparticles to generate double-conjugated gold nanoparticles (e.g., that are zwitterionic).

  • Patent number: 9533045
    Abstract: The present invention provides methods, systems, and devices for performing photothermal therapy (e.g., to treat cancer) using photothermal nanoparticles with a biocompatible coating surrounding a highly crystallized Fe3O4 core. In certain embodiments, the highly crystallized Fe3O4 core of the photothermal nanoparticles has an X-ray diffraction (XRD) pattern where the brightest diffraction ring is from the 440 plane. In some embodiments, the photothermal therapy is conducted with a device configured to emit electromagnetic radiation in the wavelengths between about 650 nm and 1000 nm, wherein the device further comprises a visible light source that allows a user to determine where the electromagnetic radiation is contacting a subject.

    Abstract: The present invention provides compositions, systems, and methods employing cleavable polymeric micelles. For example, provided herein are compositions comprising micelles that contain a hydrophobic agent (e.g., metal nanoparticles and/or therapeutic agent), where the micelles are formed from a plurality of amphiphilic polymer molecules that comprise a hydrophilic polymer and a hydrophobic polymer, where the hydrophobic polymer comprises a cleavable Furan-Maleimide adduct. Also provided herein are methods of administering such compositions to a subject and treating a localized area of the subject with a device that emits heat, NIR light, and/or alternating magnetic current such that at least some of the micelles inside the subject near the localized area are disrupted (e.g., releasing a therapeutic agent).
