Abstract
Self-assembled gold monolayers offer several advantages for the realization of novel modified electrodes for biosensor applications. This is due to their ability to decrease non-specific adsorption and provide for covalent attachment of biomolecules. Surfaces for these applications require the precise control of ligand density, the ability to immobilize ligands, and in situ-modulation of ligand activity. In this study, we focused our studies on the immobilization of antibody on a gold monolayer surface. We self-assembled thioctic acid onto the gold surface as an anchor point for the immobilization of anti-fibrinogen onto the surface. The modifications to the gold surface were characterized by ELISA, ellipsometry, and AFM.
