| 摘要 |
The present invention relates to an electrochemical sensor for the detection of biological molecules and a process for the production thereof. In the sensor, an electrode system comprising at least one working electrode ( 1 ), one counter electrode ( 3 ) and a reference electrode ( 4 ) operate inside of a reaction camber ( 18 ). The reaction chamber ( 18 ) is intended to contain a system of reagents in solution, comprising at: least one electrochemical mediator Said working electrode is made of series of nanoelectrodes ( 11, 12 ) of a noble metal, inserted in an isolating layer ( 10 ) consisting of a resin suitable for lithography and nano-lithography, functionalised or functionalisable for the binding to biological molecules to be detected. The invention further refers to a kit comprising said sensor and a process for the production thereof.
