A Terahertz Metamaterial Biosensor For Liquid Detection Combined With Microfluidic Technique

Abstract

In this paper, a terahertz metamaterial biosensor for liquid detection combined with a microfluidic technique is proposed. The model of this biosensor consists of a microfluidic channel below and metallic square split ring resonators above, leading the detect and screen abilities of this design unrelated to each other. As a result, this design allows large manufacturing errors and has a screening function and the advantage of high detection accuracy and a high degree of freedom. Because of these characteristics, this device shows great potential for the application of a label-free bio-detection in the terahertz band.
