System and method for measuring conductivity on molecular level

A method of measuring conductivity of a molecule, comprising:

• providing first and second electrodes;
• applying a potential between the first and second electrodes;
• applying a substance to be measured to the first and second electrodes;
• moving the first electrode relative to the second electrode, wherein a first step includes bringing the first and second electrodes in physical contact which forms a plurality of molecular junctions and a second step includes separating the first and second electrodes by a first distance which breaks a first molecular junction;
• and
• measuring conductivity of the substance to be measured at a plurality of distances between the first and second electrodes.
