| 摘要 |
The present invention relates to a biosensor which comprises a covalently attached monomolecular biological conjugate layer and a transducing system, wherein the biological conjugate layer has the following structural formula I:wherein,R is O or S covalently attached via a first covalent bond to the transducing device surface;X is a linker covalently attached to R via a second covalent bond and selected from a bond, linear or branched chains of 1 to 30 covalently attached atoms of at least C, N, O, Si or S, rings of at least one of C, N, O, Si or S, and a combination thereof; andP is a biological molecule stably attached to X via a third covalent bond.
