  • MRI metamaterial liner
    Patent number: 10627465
    Abstract: A metamaterial liner for an MRI bore. The metamaterial liner may cover only a portion of the MRI bore, allowing travelling wave excitations within the lined portion. By restricting the waves to the lined portion, improved signal to noise ratio may be provided. The lined length may be adjustable, for example by forming the metamaterial liner of removable annular segments. A method is provided of adjusting the length of the lined portion by removing metamaterial segments. The segments may be included in interchangeable modules. The MRI liner is suitable for any magnetic field strength, and in particular may provide improved signal to noise at reduced technical difficulty at magnetic field strengths between conventional field strengths suitable for a birdcage coil and conventional travelling wave field strengths.

  • Devices and methods for nanoparticle enhanced impedance-based molecular sensing
    Patent number: 10585094
    Abstract: An impedance based biosensor and method for detecting a target biomolecule in a sample are provided. The biosensor has a substrate, and first and second spaced-apart electrodes disposed at the substrate. A molecular recognition element (MRE) for binding with the target is bound to the substrate between the first and second electrodes. The biosensor also has a nanoparticle having an MRE bound to its surface. In the presence of the target, the nanoparticle is immobilized between the first and second electrodes due to binding of the target biomolecule with the first MRE and binding of the target biomolecule with the second MRE. A measurable change in electrical impedance across the first and second electrodes occurs due to the immobilization of the nanoparticle between the first and second electrodes.
