Abstract
A composite monolayer consisting of a thiolipid and a nucleic acid probe (1), acts as a microenvironment for probing hybridization with the complementary strand (2) by means of impedance spectroscopy. The impedance measurements indicate a significant decrease in the resistance at the electrode surface upon the formation of the (1)/(2) duplex. The impedance measurements were performed in the absence of any amplifying label or added redox label. In order to characterize the electrodes surface and to follow the immobilization processes kinetics, surface plasmon resonance measurements were performed.
