Biosensors promising bio-device for pandemic screening “COVID-19“

Mobed, Ahmad; Sepehri, Ebrahim

Undoubtedly, the coronavirus pandemic is one of the most influential events not only in medicine but also in the economic field in the world. Rapid transmission and high mortality rates, as well as prolonged and asymptomatic communal periods, are the most important reasons for the global panic due to coronavirus. Since coronavirus treatment and specific vaccines are not yet available, early detection of the virus is critical. A rapid and accurate diagnosis can play a crucial role in the treatment and control of the COVID 19 disease. Serological, ELISA, and molecular-based tests, including PCR and RT-PCR, are among the most important routine methods for detecting coronaviruses. False-positive/negative results, low sensitivity and specificity, and the need for advanced equipment are among the disadvantages and problems of routine methods. To eliminate the drawbacks of routine methods, new technologies are being developed. Biosensors are one of the most important ones. This paper is a summary of the up-to-date states of innovative bio-sensing tools for the ultrasensitive detection of coronaviruses (COVID 19) with encouraging uses for future challenges in disease diagnosis.
