Abstract
An electrochemical sensor allows even extremely small quantities or concentrations of a target chemical substance to be detected or quantified with a high precision in a particularly reliable manner. The novel sensor has a detector zone formed by nanoparticles which are embedded in a matrix and have a higher electric conductivity than the matrix material. The electric conductivity of the zone is determined by electron tunneling, ionization or hopping processes among the nanoparticles and by the electrochemical interaction thereof with a target substance to be detected.
