By integrating the hydrothermal method with the photolithography process, both the positive and negative resists were used to control the growth of nanowires through lift-off concept. The printed circuit board (PCB) was adopted as the substrate. On PCB, the interdigitated electrodes (IDE) array was firstly fabricated by etching the copper foil. Two types of chips were compared: global growth of ZnO nanowires on the device and patterned ZnO nanowires between IDE. Based on the Faraday''s law of induction, it is found that the ZnO nanowires have Faraday''s law of induction to capture electroplating solution of Metal. The detection of immobilized proteins is related to the variation of the current–voltage (I–V) characteristic curve. The experimental results show that ZnO nanowires have reliable immobilization capability for a wide range of electroplating solution concentrations. In addition, the electroplating solution from（0.16 g/L to 55 ng/L）can be detected. The chip with patterned ZnO nanowires between IDE is more sensitive than that with global growth of ZnO nanowires, even for small volume of electroplating solution.
