| titleOfInvention | Sensor and method for detecting a predetermined chemical sample in a solution |
| abstract | (57) [Summary]nA chemical sensor for measuring a change in sensor mass related to the interaction of a solution with the surface of the sensor comprises a crystal detector oscillator capable of generating a measurement signal based on a resonance frequency of the crystal detector oscillator. ing. The crystal detector oscillator has a first crystal side that is in contact with the solution and a second crystal side that is separated from contacting the solution. The first electrode is integral with the first crystal side and has an inner edge and an outer edge, an outer portion of the first crystal side outside the outer edge, and an inner portion of the first crystal side inside the inner edge. The parts are limited. The second electrode is integral with the second crystal side. The sensor adsorbs a specific complementary material, such as an antibody, to a predetermined sample on the active crystal site on the first crystal side, and then contacts the first crystal side to a solution containing the sample to form a predetermined sample. By allowing molecules to be adsorbed on active crystal sites to which complementary materials have been adsorbed, they can be used to detect the concentration of a given sample in solution. The difference between the measured resonance frequency of the sensor adsorbing the complementary material and the measured resonance frequency of the sensor adsorbing the complementary material plus the sample represents and correlates to the concentration of the given sample in the solution. Can be. The sensor can also be used to measure changes in sensor mass related to degradation of the coating deposited on the first crystal side. The apparatus of the present invention comprises a chemical sensor operatively coupled to detection means for detecting a resonance frequency of the crystal detector oscillator and generating a detector output signal indicative of the resonance frequency of the crystal detector oscillator. The apparatus can further include display means operatively coupled to the sensor detection means for displaying a detector output signal. |
