Abstract
The present invention provides an integrated type microfluidic electrochemical biosensor system for rapid biochemical analysis and the usage of the system. The system comprising: a continuous feeding unit for sequentially conveying lead eluent, sample solution, sample eluent, signal probe solution, signal probe eluent and electrochemical detection buffer solution; a microfluidic chip consists of one or more micro-channel network, the microfluidic chip covers the electrode array to form a channel system, capture probes which have interaction with the said sample solution fixed on the surface of the electrode array, said channel system is connected with the continuous feed unit; and a power system for providing power to said continuous feeding unit. The invention innovatively combine three technologies of planar electrode arrays, microfluidic chip technology and continuous feeding unit together, and the integrated type microfluidic electrochemical biosensing system which is small in size and low in cost and has a wide application prospect is provided.
