Abstract
Disclosed is a microfluidic sensor complex structure comprising a lower plate, a middle plate and an upper plate. A reference electrode, a working electrode and an electrode connection are formed on the lower plate. The middle plate comprises a microfluidic channel passage therein. The upper plate is overlaid on the middle plate so as to induce a capillary phenomenon on the microfluidic channel passage formed on in the middle plate. The microfluidic sensor complex structure allows the motion of a sample to be driven only by a capillary phenomenon, without additional operation, and allows an immune response, washing, and electrochemical analysis in one round once a sample is introduced thereinto. Hence, it requires only a short time period for measurement, is convenient to handle, and shows sensitivity and selectivity. Also, it can be produced on a mass scale because it can be formed of typical organic polymers using a simple method. Based on analytical electrochemistry, the microfluidic sensor complex structure can be used as a small-size sensor that can be applied to practice sites.
