Radio frequency label type biosensor

Abstract

The invention provides a radio frequency label type biosensor. The radio frequency label type biosensor comprises a piezoelectric base; an interdigital transducer, a reference channel and a detection channel are sequentially and abreast arranged on the piezoelectric base, wherein the reference channel is used for setting a reference biological probe and a PBS (Phosphate Buffer Solution) buffer solution, and the detection channel is used for setting a detection biological probe and a substance to be detected; and a reflecting grating I, a reflecting grating II and a reflecting grating III are also arranged on the piezoelectric base, wherein the reflecting grating I is arranged between the interdigital transducer and the reference channel, the reflecting grating II is arranged between the reference channel and the detection channel, and the reflecting grating III and the reflecting grating II are arranged at one side of the detection channel in a symmetrical mode along the axis of the detection channel. The ratio frequency label type biosensor has the advantages of compact structure, convenient use and low manufacturing cost.

Description

technical field [0001] The invention belongs to the field of sensors, in particular to a radio frequency tag biosensor. Background technique [0002] A biosensor is an instrument that is sensitive to biological substances and converts its concentration into electrical signals for detection. It uses immobilized biosensitive materials as recognition elements (including enzymes, antibodies, antigens, microorganisms, cells, tissues, nucleic acids, etc.) Active substances) and appropriate physical and chemical transducers (such as oxygen electrodes, photosensitive tubes, field effect tubes, piezoelectric crystals, etc.) and signal amplification devices constitute analytical tools or systems. [0003] Radio frequency identification is RFID (Radio Frequency IDentification) technology, also known as electronic tags and radio frequency identification. touch. [0004] Existing biosensors are often complex in structure and expensive, and by integrating the technical principle of radi...
