  • Patent number: 11369681
    Abstract: The invention discloses nanoparticles comprising compounds of calcium with anions such as phosphate, pyrophosphate, sulphate, silicate, carbonate, molybdate, or phosphosilicate that are doped with various ions. The nanoparticles are configured to produce heat (hyperthermia) under radio-wave (1 KHz-1000 GHz) exposure together with magnetism suitable for contrast imaging in MRI, X-ray absorption for computed tomography, near-infrared optical fluorescence for optical imaging, and/or radio-isotope emission for nuclear imaging or therapy. The nanoparticles can also be incorporated into micro-beads or other 3 dimensional scaffolds for image-guided (MRI, CT, NIR, nuclear) tissue regeneration, immunotherapy, vascular or tumor embolization, and/or chemo/radio-embolization.

  • Patent number: 10806805
    Abstract: A composite implant for providing simultaneous magnetic resonance imaging (MRI) and computed tomographic (CT) imaging contrast is disclosed. The composite implant is formed of a calcium compound in the form of nano or microparticles doped with a first dopant configured to provide MRI contrast and a second dopant configured to provide CT contrast. The calcium compound is loaded onto a polymer gel matrix and lyophilized to form a mass with 3-dimensionally interconnected porosity, configured to provide tissue integration and proliferation sites. Methods of forming the composite implant are also disclosed. The implant could be a scaffold or bead structured to enable treatment of human or animal patient for bone/cartilage injury or defect by implantation, with MRI and CT monitoring.

  • Publication number: 20190167822
    Abstract: The invention discloses non-iodinated radiopaque microbeads that may be used in image guided embolization in a subject ailing with tumor. The non-iodinated radiopaque microbeads include a ceramic material doped with a CT contrast agent or a MRI contrast agent or both. The doped ceramic is blended with a polymer and the blend is electrosprayed to form the radiopaque microbeads. Further the radiopaque microbeads are radiolabeled with a radioactive isotope. Methods of synthesis of the radiopaque microspheres are also disclosed. The non-iodinated radiopaque microbeads with radiolabeling are capable of rendering an imageable computed tomography (CT) contrast or magnetic resonance imaging (MRI) contrast when administered in a subject. Also the microspheres are biodegradable and hence the treatment could be repeated in case of recurrence of the tumor in the subject.
