| 摘要 |
<p>The present invention concerns a sensor for detection of a biological analyte in a test sample. The biological analyte is a member of a pair forming group such as antigen/antibody, ligand/receptor, etc. The sensor comprises a porous matrix where in each cavity are entrapped a molecule capable of specifically binding to the analyte as well as an analyte-analogue. Competitive displacement of the analyte-analogue by the assayed analyte bring to change at least one detectable property of the sensor.</p> |
