Abstract

A method developed to determine the conductance of single molecules covalently bonded to gold electrodes is discussed. In the method, the molecular junction is formed by separating two Au electrodes from contact in a solution containing the sample molecules. The discrete drop in the conductance, accompanied by a discrete drop in the force between the two electrodes, allows the determination of bonding strength of molecule to the electrode. The method is found to be efficient in measuring the conductance single molecules, helping to study the biological molecules under physiological conditions.
