  • Biosensors comprising a covalently attached monomolecular biological conjugate layer and a transducing device
    Patent number: 6770179
    Abstract: 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: —R—X—P  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; and P is a biological molecule stably attached to X via a third covalent bond.

  • Process for modification of implant surface with bioactive conjugates for improved integration
    Patent number: 5824651
    Abstract: The present invention relates to a process for the covalent coating of implants with a bioactive conjugate, which comprises the steps of: a) cleaning a metal implant surface from contaminants by deoxidation with potentiostatic electrochemical polishing in a solution selected from ethanol, perchloric acid-butanol-methanol solution, H.sub.2 O.sub.2 --NaCl--NaH.sub.2 PO.sub.4 or by chemical cleaning with a solution selected from the group consisting of HF/HNO.sub.3, H.sub.2 O.sub.2 /H.sub.2 SO.sub.4 and H.sub.2 O.sub.
