    摘要: A system and method for locating magnetic material. In one embodiment the system includes a magnetic probe; a power module in electrical communication with the magnetic probe to supply current to the magnetic probe; a sense module in electrical communication with the magnetic probe to receive signals from the magnetic probe; and a computer in electrical communication with the power module and the sense module. The computer generates a waveform that controls the supply of current from the power module and receives a signal from the sense module that indicates the presence of magnetic material. The magnetic probe is constructed from a material having a coefficient of thermal expansion of substantially 10−6/° C. or less and a Young's modulus of substantially 50 GPa or greater. In one embodiment magnetic nanoparticles are injected into a breast and the lymph nodes collecting the particles are detected with the probe and deemed sentinel nodes.

    摘要: Disclosed are compositions and methods related to clot binding compounds. For example, disclosed are conjugates comprising a surface molecule and a plurality of clot binding compounds. The clot binding compounds can selectively bind to clotted plasma protein. The conjugate can, for example, cause clotting and amplify the accumulation of the conjugate in tumors. In one example, the conjugate can comprise a sufficient number and composition of clot binding compounds such that the conjugate causes clotting and amplifies the accumulation of the conjugate in tumors. The disclosed targeting is useful for treatment of cancer and other diseases and disorders.

    摘要: The various embodiments herein provide for the engineered multimodal super paramagnetic iron oxide nanoparticles (SPIONs) with a fluorescent dye. The SPIONs comprise fluorescent polymer dye arranged in a gap between a SPION core and a gold shell. The SPIONS are provided with a gold coating. The gap is made up of a polymeric molecule such as 6-arm anthracene terminated. The core of the nanoparticle is made up of a magnetic metal oxide. The method for synthesizing SPIONs involves preparing carboxyl-dextran complex and the SPIONS. The SPIONs are coated with carboxyl-dextran complex. The coated SPIONs coated are subjected to fluorescent polymer and gold nano shell coating. The prepared SPIONs are characterized by light scattering measurement and magnetization measurements.

    摘要: The present invention relates to a nano-composite containing anionic and cationic polymers and a method for preparing thereof, and more particularly to a poly-gamma-glutamic acid (γ-PGA)/chitosan/manganese iron oxide nanoparticle composite prepared by encapsulating iron oxide-based nanoparticles in a γ-PGA/chitosan polymer composite using the ionic self-assembly properties of poly-gamma-glutamic acid (γ-PGA) and chitosan, which are biocompatible polymer materials, and to a method for preparing thereof.The present invention provides a magnetic resonance imaging nano-contrast agent based on a nanoparticle composite including iron oxide-based nanoparticles encapsulated in a self-assembled composite of anionic poly-gamma-glutamic acid (γPGA) and cationic chitosan. The iron oxide-based nanoparticles encapsulated in the composite interact with each other to produce a synergistic effect on the amplification of magnetic resonance signals, and thus have an relatively excellent contrast effect compared to when they exist as single particles.
