Sensor Development for Coronavirus

Severe acute respiratory syndrome (SARS) is a highly infectious disease that results death in a great proportion of patients. SARS is caused by the SARS coronavirus; these viruses are real danger to human safety. The recent outbreak of COVID-19 disease is an infectious disease caused by a newly discovered coronavirus (CoV) that belongs to the single-stranded, positive-strand RNA viruses. CoV is a dangerous threat to public health, economics, and global disciples. Therefore, it is important to identify, isolate, and treat individuals at early stages of the disease to control its spread. Because this virus is new and because of the lack of any approved drug or vaccine, there is an urgent need for highly specific and sensitive diagnostic devices to identify infected people. In the present scenario, various analytical tools are available for the detection of several kinds of viruses through the use of different types of biosensing technologies. During the past decades, biosensors have emerged as reliable analytical devices and provide new promising tools for the detection of viruses. Recently, research on biosensors has attracted great attention of technological scientists because of their inherent properties and high sensitivity and selectivity. The present chapter summarizes the utilization of nanomaterials in the development of biosensing devices for the detection of the pathogenic virus, CoV. In addition, it describes the fabrication of methodology, mechanism of sensing, and principle used for transducing.
