| 20090233375 | Thermal bath systems and thermally-conductive particulate thermal bath media and methods - Thermally-conductive laboratory bath media can be used to replace conventional wet media or dry solid blocks in existing thermal baths for heating or cooling samples with advantageous maintenance and microbial control benefits. The media is typically in the form of metallic or metallic-coated pellets that have rounded edges, hardened surface, a smooth polished finish, and are sized small for efficient thermal communication between pellets and samples. Laboratory bath improvements are disclosed with various advanced controls and adaptations for thermal control as well as infection control. | 09-17-2009 |
| 20100093104 | Method and apparatus for positioning nano-particles - A method of positioning a sample at a desired location relative to a magnetic sensor, for measurement of magnetic characteristics of the sample. A sample mounting substrate is provided, and an amphifunctional molecule is bound to the sample mounting substrate at the desired location. The amphifunctional molecule has a portion for binding to the sample mounting substrate, and a portion for capturing the sample. The sample is then provided for capture by the amphifunctional molecule. | 04-15-2010 |
| 20100129925 | SEMICONDUCTOR NANOWIRES CHARGE SENSOR - A semiconductor nanowire is coated with a chemical coating layer that comprises a functional material which modulates the quantity of free charge carriers within the semiconductor nanowire. The outer surface of the chemical coating layer includes a chemical group that facilitates bonding with molecules to be detected through electrostatic forces. The bonding between the chemical coating layer and the molecules alters the electrical charge distribution in the chemical coating layer, which alters the amount of the free charge carriers and the conductivity in the semiconductor nanowire. The coated semiconductor nanowire may be employed as a chemical sensor for the type of chemicals that bonds with the functional material in the chemical coating layer. Detection of such chemicals may indicate pH of a solution, a vapor pressure of a reactive material in gas phase, and/or a concentration of a molecule in a solution. | 05-27-2010 |
| 20120171775 | MULTI-DIMENSIONAL INTEGRATED DETECTION AND ANALYSIS SYSTEM (MIDAS) BASED ON MICROCANTILVERS - The present invention is a multidimensional integrated detection and analysis system (MIDAS) for any gas or fluid that transfers or accepts electronic charge (including but not limited to CH | 07-05-2012 |

| 20140193924 | INSTRUMENTS FOR MONITORING ELECTROSTATIC PHENOMENA IN REACTORS - Probes for monitoring electrostatic phenomena in challenging environments, such as fluidized bed reactors. These probes include a coated or uncoated static probe for measuring electric field and or particle charge state, an oscillatory electric field probe for measuring electric field, a chopped electric field probe for measuring electric field, and a radio-frequency antenna probe for detecting electrostatic discharges. | 07-10-2014 |
| 20140199774 | Wireless Chemical Sensor and Sensing Method for Use Therewith - A wireless chemical sensor includes an electrical conductor and a material separated therefrom by an electric insulator. The electrical conductor is an unconnected open-circuit shaped for storage of an electric field and a magnetic field. In the presence of a time-varying magnetic field, the first electrical conductor resonates to generate harmonic electric and magnetic field responses. The material is positioned at a location lying within at least one of the electric and magnetic field responses so-generated. The material changes in electrical conductivity in the presence of a chemical-of-interest. | 07-17-2014 |
| 20140342463 | Nanoscale Spintronic Chemical Sensor - In general, the present disclosure is directed toward a novel hybrid spintronic device for converting chemical absorption into a change in magnetoresistance. This device uses a novel magnetic material which depends on the attachment of an organic structure to a metallic film for its magnetism. Changes in the chemical environment lead to absorption on the surface of this organometallic bilayer and thus modify its magnetic properties. The change in magnetic properties, in turn, leads to a change in the resistance of a magnetoresistive structure or a spin transistor structure, allowing a standard electrical detection of the chemical change in the sensor surface. | 11-20-2014 |
| 20150017735 | Analyte sensor and analyte sensing method - A biosensor includes a detection element having an analyte detecting portion which is monotonically increased in mass in response to detection of an analyte; a reference element having a reference measuring portion which exhibits no reactivity to the analyte; a mixer which mixes a detection signal responsive to mass variations in the analyte detecting portion from the detection element and a reference signal from the reference element; a measurement which calculates two candidate phase-change values of a positive value and a negative value, from a signal mixed by the mixer in accordance with a heterodyne system, and determines a phase-change value from the two candidate phase change value by judging whether the phase is positive or negative based on temporal changes in signal strength; and a detection amount calculation portion which calculates a detection amount of the analyte based on the phase change value determined by the measurement portion. | 01-15-2015 |
