20150192548 | ARRAY OF RESONANT SENSORS UTILIZING POROUS RECEPTOR MATERIALS WITH VARYING PORE SIZES - A sensor array comprises resonant sensors and porous receptor materials arranged on the resonant sensors to absorb or adsorb one or more analytes. The average pore size of the porous receptor materials on the sensors increases systematically from one sensor to the next in the array. At least one detector is arranged to detect responses of the resonant sensors when the array is exposed to a sample potentially containing one or more of the analytes. In some embodiments, a processor is programmed to determine from the sensor responses the presence, amount or relative concentration of target molecules in the sample. | 07-09-2015 |
20150177196 | Differential Humidity Sensor - A sensor array includes at least first and second resonator sensors. A receptor material on the first sensor is hydrophilic relative to a receptor material on the second sensor, and the receptor material on the second sensor is hydrophobic relative to the receptor material on the first sensor. At least one detector measures sensor responses when masses of one or more of substances are adsorbed or bound to the sensors. A processor receives signals or data representative of the sensor responses. The processor is programmed to determine at least one humidity value according to the sensor responses. | 06-25-2015 |
20150011428 | Array of Sensors with Surface Modifications - Surface modifications to sensors in an array give the sensors different functionalities for adsorbing or binding molecules. A first sensor in the array includes a first resonating member having a first surface comprising a polymer receptor material coated over a first underlying material. A second sensor includes a second resonating member having a second surface comprising the polymer receptor material coated over a second underlying material that is different than the first underlying material. The first underlying material, the second underlying material, and the polymer receptor material are selected such that the first resonating member, having a combination of the polymer receptor material and the first underlying material, has a different ability to adsorb or bind a mass of one or more analytes than does the second resonating member having a combination of the polymer receptor material with the second underlying material. Methods for fabricating sensors with surface modifications are also provided. | 01-08-2015 |
