Abstract

A terahertz metamaterial biosensor with integrated microfluidic is proposed in this paper. The sensor integrates a microfluidic between the traditional metal resonant structure and the metal base plate, which can produce a perfect absorption peak at 0.827 THz, and the refractive index sensitivity is 225.1GHz/RIU. The research results of this paper show that the existence of microfluidic significantly expands the overlap of electromagnetic wave and analyte and enhances the coupling reaction, which can not only realize the direct detection of liquid samples, but also greatly improve the sensitivity of the sensor..
