Abstract
A plasmonic waveguide (), a biosensor chip () and a system, wherein the plasmonic waveguide () is applied to the biosensor chip (), and comprises a base () and a plasmonic structure () provided on the upper surface of the base (); the plasmonic structure () comprises a plurality of plasmons () periodically arranged, the plasmons () being metal split rings, and the annular openings of the plasmons () being used for fixing antibody probes (). The plasmon waveguide () is provided in the biosensor chip (), the target biomolecules in the detection liquid flowing into a microfluidic channel () can be captured by means of the antibody probes (), and the plasmonic waveguide () is used to enhance the signal strength of terahertz waves emitted to the biosensor chip (), thereby enhancing the signal strength of the reflected terahertz waves detected by a terahertz analyzer (), improving the detection sensitivity, the signal-to-noise ratio and the reliability.
