The Review of Biosensor and its Application in the Diagnosis of COVID-19

The objective of this article is to summarize the available technologies for biosensing applications in COVID-19. The article is divided into three parts, an introduction to biosensing technologies, applications of mainstream biosensing technologies and a review of biosensing applications in COVID-19. The introduction of biosensors presents the history of inventing the biosensing technology, which refers to the ISFET. The resonant biosensor with the example of MEMS. the principle of optical biosensor, and the thermal biosensor. In the second part, the main use of biosensing techniques, it was discussed the field of the food industry, environmental monitoring, and the medical industry. In the part of biosensor application in COVID-19, it was mentioned that the technique of POCT, the use of RT-LAMP-NBS in the early detection in China, and the use in gRT-PCR for the detection of the DNA code to determine the presence of pathogen of COVLD-19 in the human body.
