Study Description: This project was in response to the NIH's RADx-rad Emergency Responses to the COVID-pandemic for new or non-traditional technologies developed for single extracellular vesicle, exosome and extracellular RNA (exRNA) isolation and analysis and reposition them for detection of SARS-CoV-2. The project's group was a grantee in the NIH Common Fund Extracellular RNA Communication (ERC) Program advancing a new and emerging technology of Acoustofluidic Separation (AFS) for label-free, high yield and purity exosomes from biofluids which is coupled to extracellular RNA characterization using Surface Enhanced Raman Spectroscopy (SERS) for single EV identification. This project was to reposition the AFS EV technology and SERS for the non-invasive earliest detection of SARS-CoV-2 in saliva of infected patients. Host immunity to SARS-CoV-2 was also assessed in the saliva samples, permitting the earliest detection of SARS-CoV-2 infection and host immunity non-invasively in a saliva sample.
