Abstract

A new impedeance spectroscopy unit is developed fully customized to become a vital part of label free biosensor arrays with possible applications in DNA and protein sensing Test measurements are conducted to expolre the accuracy and specificity of the system, both under electronic lab conditions as well as under wet cell conditions with synthetic-diamond based sensor electrodes. The impedance of seven resistors was monitored for 17h and a maximum error
