| 摘要 |
The present invention discloses a biosensor and a method using the same to perform a biotest. The biosensor of the present invention integrates a SAW (Surface Acoustic Wave) device and a test polymer to detect an analyte in a liquid specimen. The test polymer reacts with the analyte. After reaction, the substantial weight decrease of the test polymer causes the variation of the SAW characteristics. The attributes and content of the analyte is detected and determined according to the variation of the SAW characteristics.
