Abstract: 

Current diagnostic approach to detect the SARS-CoV-2 is based on detection of the viral RNA in swab samples using quantitative PCR (qPCR). The qPCR technology is relatively accurate, but available devices are bulky, expensive, and employ laborious and lengthy protocols that take ~2–3 hours. Current serological assays to detect the anti-viral IgG/IgM antibodies in serum are rapid (~10 minutes), but have very low sensitivity, and therefore cannot be used to rule out the disease. Here, using an optical modulation biosensing (OMB) technology, we demonstrate highly sensitive molecular assays for rapid detection of the viral RNA, as well as quantitative serological assays to detect specific anti-SARS-CoV-2 antibodies in blood samples. Previously, we demonstrated that the technology is 4–9 times faster than qPCR and provide results within 20-30 minutes instead of hours. A prototype of the platform has been successfully used to test hundreds of suspected Zika samples with much higher sensitivity and specificity than the current state-of-the-art tests. Our advances will be applicable to a broad spectrum of serological and nucleic acids-based virus detection assays, enabling rapid response in future viral outbreaks and providing benefits to a wide range of health applications.
