Abstract: A cross-modal interface includes a multi-modal sensor configured to concurrently receive multiple input signals with each input signal being provided from a different imaging modality and in response thereto providing a single cross-modal output signal to processing circuitry which processes the single cross-modal output signal provided thereto and generates an output comprising information obtained or otherwise derived from each of or a combination of the different imaging modalities.

Abstract: Embodiments described herein relate to detectors and their method of use for sensing electromagnetic fields, electromagnetic signals, biochemical analytes, and/or other conditions in subjects. The device may include an inductively-coupled implantable coil-based transducer that converts electrical, photonic, biochemical signals, and/or other appropriate signals and/or conditions originating in tissues and/or transplanted tissue grafts into changes in a property of the transducer, such as a resonance frequency, that may be detected using an alternating magnetic field that may be provided by a magnetic resonance imaging (MRI) signal and/or other appropriate source. In some embodiments, the detector comprises a FET that changes state upon detection of a subject condition of interest. The change in the FET may change the resonance frequency of an associated LC or RLC circuit.

Abstract: The present disclosure provides imaging and contrast agents, and methods of using the agents. According to some embodiments of the disclosure, agents and methods for magnetic resonance imaging and related technologies are provided.

Abstract: The present disclosure generally relates in certain embodiments to a magnetic imaging kit for biochemical sensing, e.g., for detection of analytes, via magnetic imaging techniques. For instance, in one set of embodiments, the kit comprises a collection of magnetic imaging agents (e.g. superparamagnetic iron oxide nanoparticles) and linker species (e.g. a catechol, phosphothreonine, and/or derivative thereof) with a molecular weight of less than or equal to 1000 Da, or less than or equal to 500 Da. The magnetic imaging agents may sense the presence of an analyte via aggregation or disaggregation of the two or more magnetic imaging agents. In addition, certain aspects are directed to a method of exposing two or more magnetic imaging agents to a region on or in a subject and imaging the region to determine the analyte.

Abstract: The disclosure relates in some aspects to imaging agents, and in particular, imaging agents for sensing of calcium signaling. According to some embodiments of the disclosure, contrast agents for magnetic resonance imaging and related technologies are provided, and methods of making and using the contrast agents.

Abstract: The present invention generally relates to agents and compositions having MRI and/or optical signals, and methods for their use in the determination of an analyte. In some cases, an optical, MRI, or other signal produced by the agent or composition may be affected by the presence of an analyte. Some embodiments of the present invention may provide agents or compositions which are cell permeable. Examples of analytes that may be determined by the present invention include zinc ions, calcium ions, and other biological analytes.
