Coronavirus particle detection device

Abstract

The invention provides a coronavirus particle detection device, and relates to the technical field of virus detection. The coronavirus particle detection device comprises a quartz substrate, a blowing nozzle and a spin wave interferometer, ferromagnetic fluid is arranged on the quartz substrate, the blowing nozzle is connected with the quartz substrate, the spin wave interferometer is connected with the ferromagnetic fluid, the ferromagnetic fluid is suitable for generating magnetic change after air or aerosol with coronavirus particles is blown into the blowing nozzle, and coherent spin waves of the spin wave interferometer are suitable for generating phase difference change after the magnetic change of the ferromagnetic fluid. According to the technical scheme provided by the invention, the ferromagnetic fluid is set to generate magnetic change after being in contact with air or aerosol with coronavirus particles so as to cause phase difference change of coherent spin waves of the spin wave interferometer, whether the coronavirus particles are contained or not can be determined by detecting the phase difference change of the coherent spin waves, and rapid detection of the coronavirus particles is realized.

Description

technical field [0001] The invention relates to the technical field of virus detection, in particular to a coronavirus particle detection device. Background technique [0002] Coronaviruses are a large class of RNA viruses that exist widely in nature and can infect mammals, birds, and amphibians. A coronavirus particle (virion) consists of a spherical lipid envelope containing nucleic acid (capsid) and spines (spikes). Because the spikes of the virus particle resemble the corona of the sun, they are named coronaviruses. Under the action of the virus envelope, the virus particles are adsorbed on the cell surface and enter the cell by binding to protein receptors located on the cell membrane. [0003] One of the important measures to deal with the coronavirus pandemic is to be able to quickly identify and isolate coronavirus carriers, so it is necessary to detect coronaviruses at an early stage when they do not show typical symptoms. Although the PCR (Polymerase Chain Reacti...

AI Technical Summary

Problems solved by technology

Although the PCR (Polymerase Chain Reaction, polymerase chain reaction) method can detect coronaviruses in the body early, the detection swabs need to be transported to a laboratory with high cleanliness and tested by specialized operators, usually 6-12 days. The test results can only be obtained after hours, so the detection of the PCR method takes a long time. During this period, the coronavirus carriers may cause the spread of the coronavirus in a large area
