Abstract:
COVID-19 is a novel respiratory infectious disease caused by severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2). The continuous emergence of SARS-CoV-2 variants poses a serious threat to the public health. A bedside device with high specificity and sensitivity for real-time and rapid detection is of great value for the prevention and control of COVID-19. Moreover, understanding the transmission behavior of airborne pathogens such as SARS-CoV-2 is also vital for scientific disease prevention. Biosensors are devices that can convert biomolecular reaction signals into detectable physical or chemical signals and have been increasingly used for the detection and analysis of pathogenic microorganisms. Biosensors bases on the conventional detection methods such as colony counting, immunoassays and molecular techniques are often time-consuming, labor-intensive and complicated. Nanomaterial-based biosensors are more portable and can be used for rapid on-site detection. This review summarized the progress in biosensors for pathogen detection and the application of nanomaterial based-biosensors in the surveillance of airborne pathogens.
