Conductance of the biochips measured as a function of silver enhancing time. (Inset) Conductance measurement in logarithmic domain, which can clearly show that the biomolecular transistor exhibits three different types of responses (labeled as A, B, and C) based on the nature of the conductive path across the electrodes. A cutoff region; B sub-threshold region when the formation of the conductive bridge between the electrodes is incomplete; C above-threshold region where the bridge is completely formed by silver-enhanced gold nanoparticles leading to a step increase in conductance and conductance slope
