MULTI-FREQUENCY POINT RESONANCE BIOSENSOR, ITS PREPARATION METHOD AND USE THEREOF IN CELL CONCENTRATION DETECTION

WIPO Patent Application WO/2020/211306

A1

The present invention provides a multi-frequency point resonance biosensor, a preparation method thereof and a method for detecting cell concentration with the biosensor. The multi-frequency point resonance biosensor comprises a plurality of basic units. The basic unit comprises a metal layer and a dielectric layer: the metal layer is composed of an asymmetric U-shaped structure and a rectangular antenna structure. The metal layer comprises a metal upper layer and a metal lower layer, wherein the metal upper layer is made of gold, and the metal lower layer is made of titanium. The dielectric layer comprises polyimide film. The biosensor of the invention can realize high-sensitivity cell sensing with fast and multi-resonance label-free detection in the terahertz frequency.
