    摘要: The present invention teaches a process for fabrication of quantum-well devices, in which the quantum-wells are configured as small islands of GaAs in an AlGaAs matrix. Typically these islands are roughly cubic, with dimensions of about 100 Angstroms per side. To fabricate these, an n- on n+ epitaxial GaAs structure is grown, and then is etched to an e-beam defined patterned twice, and AlGaAs is epitaxially regrown each time. This defines the quantum wells of GaAs in the AlGaAs matrix, and output contacts are then easily formed.

    摘要: A three-terminal quantum well device, which functions somewhat analogously to an MOS transistor. That is, the three terminals of the device can generally be considered as source, gate, and drain. An output contact is connected by tunneling to a number of parallel chains of quantum wells, each well being small enough that the energy levels in the well are quantized discretely. In each of these chains of wells, the second well is coupled to a common second conductor, and the first well is electronically coupled to a common first conductor.

    摘要: The present invention relates to a device and method for determining the presence of a specific compound in solution. The device includes a nanosensor having an electrically conducting pathway between at least a first and second contact. The device also includes a first receptor, suitable for binding a specific compound in the solution, attached to the nanosensor, and a second receptor also suitable for binding the specific compound while the specific compound is bound to the first receptor. The second receptor is attached to an enzyme added to the solution. When the solution having the second receptor is added to the device, and a second compound that is a substrate for the enzyme is subsequently added to the solution, a measured difference in an electrical property in the device before and after the application of the second compound is indicative of the presence of the specific compound in the solution.

    摘要: An apparatus and method for separating an analyte from a test sample, such as bacteria from blood components, based on their dielectric properties, localizing or condensing the analyte, flushing substantially all remaining waste products from the test sample, and detecting low concentrations of the analyte. Species movement is caused by a module array imparting opposing dielectrophoretic forces. The module array includes a plurality of microfluidic channels with connecting microfluidic waste channels for directing undesired material away from the analyte. An electric field is applied causing a positive dielectrophoretic force to the analyte to capture the analyte. The Clausius-Mossotti factor of the analyte is changed by flushing the analyte with a reference solution, which causes a negative dielectrophoretic force to facilitate release of the analyte. A field effect nanowire or nanoribbon sensor detects the analyte after capture.

    摘要: The present invention relates to uniform nanostructure biosensors and methods of calibrating the response of nanostructure biosensors. The invention overcomes device to device variability that has made quantitative detection difficult. The described biosensors have uniform characteristics that allow for more reliable comparison across devices. The methods of the invention comprise normalizing the initial current rate, as measured by the nanostructure biosensor following the addition of an analyte, to device characteristics of the biosensor. The device characteristics of the biosensor which can be used to normalize the response include baseline current and transconductance. Calibration of responses allows for the generation of calibration curves for use in all devices to quantitatively detect an analyte, without the need for individual device calibration.
