20090291509 | Sensing method - To enable successive measurement of samples by using one piezoelectric sensor. An adsorption layer provided in a piezoelectric sensor is an adsorption layer in which protein and an immunoglobulin are stacked in this order from the bottom. The immunoglobulin has a property of separating from protein when coming into contact with an acid liquid, and therefore, when the immunoglobulin as the adsorption layer is brought into contact with the acid liquid after capturing a substance to be sensed, the immunoglobulin is separated from the protein. Then, the adsorption layer is again formed by the supply of a new immunoglobulin, which enables the successive measurement of samples. | 11-26-2009 |
