Abstract: An imaging system for imaging an object, including: a support member adapted to receive the object in an immobilized state; a removable phosphor plate assembly adapted to respond to ionizing radiation by emitting visible light; first imaging means for imaging the immobilized object in a first imaging mode to capture a first image; second imaging means for imaging the immobilized object in a second imaging mode, different from the first imaging mode, to capture a second image; and third imaging means for imaging the immobilized object in a third imaging mode, different from the first and second imaging modes, to capture a third image, wherein the first imaging mode uses the phosphor plate assembly and is selected from the group: x-ray mode and low energy radio isotope mode; the second imaging mode uses the phosphor plate assembly and a high energy radio isotope mode, and the third imaging mode is selected from the group: bright-field mode, fluorescence mode and luminescence mode.

Abstract: A method and a device are disclosed for transdermal delivery to an animal or human of biological cargo-laden nanoparticles. The particles may include multimodal optical molecular imaging probes. The particles may be delivered by providing them in a form that can be absorbed through the skin and applying them to the skin of an animal or human. The application may be accomplished using biological cargo-laden nanoparticles in a device attachable to the skin. The device may be attached directly to the skin by a device containing a vasodilating agent or agents, or micro needles, or multi-layer time release material. The biological cargo-laden nanoparticles may comprise drugs, vaccines, bio-pharmaceuticals, imaging contrast agents, multimodal imaging contrast agents, biomolecules, or anti-infectives. The device may include a first plurality of different types of biological cargo-laden nanoparticles located in a corresponding second plurality of separate time release layers.

Abstract: A method is taught that provides for transmucosal delivery of a biological cargo and optical molecular imaging probes to a subject animal or human. At least one biological cargo-laden nanoparticle imaging probe is provided in a form that will be absorbed via mucosal tissue. The biological cargo-laden nanoparticle imaging probe is delivered to the mucosal tissue of the animal or human. The method further may include steps of providing a support member adapted to receive the subject in an immobilized state; positioning the subject on the support member; and after the delivering of the imaging probe, imaging the immobilized subject using a multimodal imaging system.

Abstract: An apparatus for multimodal imaging of an object includes a support stage for receiving an object to be imaged; an object supported on the stage, a light source for producing a beam to illuminate the object; a filter positioned to receive and pass the beam toward the object; and a lens and camera system for capturing an image of the object. The apparatus may include a tiltable filter for filtering light from the source.

Abstract: A dry, removable analytical element can be used to detect chemiluminescent signals produced from the reaction of peroxidase and a chemiluminescent detection system. The analytical element contains at least two layers, the outer layer being non-tacky and water-soluble or water-permeable, and used to contact a gel plate or transblotting membrane in which multiple analytes are located. The resulting signal can be recorded using a photosensitive element. Test kits include the various packaged components needed to use the analytical element for analyte detection. Within the element are critical amounts of oxidase and an oxidase substrate for highly sensitive analyte detection.
