Label-free, dual-analyte electrochemical biosensors: a new class of molecular-electronic logic gates

J Am Chem Soc. 2010 Jun 30;132(25):8557-9. doi: 10.1021/ja101379k.

Abstract

An "XOR" gate built using label-free, dual-analyte electrochemical sensors and the activation of this logic gate via changing concentrations of cocaine and the relevant cDNA as inputs are described.
