Proposal Title: “Rapid, Low-Cost Detection of COVID-19 in Self-Administered Human Saliva Samples Using Printed Graphene Electrochemical Sensor”

Funding Source: Office of the Vice President for Research

As testing for COVID-19 continues to be a complicated, costly, and often unpleasant process, Claussen and Gomes contend that there is a critical need to develop a simple, low-cost, and accurate technique for diagnosis. The team’s proposed testing system would use self-collected human saliva samples instead of nasal swabs administered by a medical professional. The alternate system would be able to provide results in approximately 20 minutes and would not require lab equipment or trained personnel. The technology could be used to check for COVID-19 before employees enter their place of work each day, or to help patients know if they are virus free and able to exit self-quarantine. Each test kit would cost less than $6 — compared to $35.92 for COVID-19 tests developed by the Centers for Disease Control and Prevention and $51.33 for commercial tests.
