Abstract: Systems and methods for magnetic targeting of therapeutic particles are provided. Therapeutic particles comprise one or more magnetic or magnetizable materials and at least one therapeutic agent. Therapeutic particles are specifically targeted using uniform magnetic fields capable of magnetizing magnetizable materials, and can be targeted to particular locations in the body, or can be targeted for capture, containment, and removal. Also provided are bioresorbable nanoparticles prepared without the use of organic solvents, and methods for therapeutically using such bioresorbable nanoparticles.

Abstract: The present invention relates to a new hydrogel functionalized with a polymerizable moiety, the polymerized hydrogels, films and gels comprising the same and their use for cells, proteins, DNA or other molecules encapsulation, including use as biosensors or bioreactors.

Abstract: A therapeutic system and a method that uses stents, and/or other implantable devices (104) for local delivery of a therapeutic agent is disclosed. A therapeutic formulation (102) may include particles of a biocompatible magnetic or magnetizable material that carry the therapeutic agent, or magnetically responsive cells. The therapeutic formulation (102) is intravenously administered to a mammalian subject. A portion of the formulation (102) is delivered to the proximity of a device (104) implanted in the vascular system of the subject by externally generating a magnetic field gradient (106) on the implantable device (104). The portion of the therapeutic formulation (102) not delivered to the proximity of the implantable device (104) is removed from the vascular system. The method allows for the repeated administration of the same or different therapeutic agent, and further, has the option of locally injecting, or alternatively, peripherally administering, the therapeutic agent.
