Rapid COVID-19 diagnostic test delivers results within 4 minutes with 90 percent accuracy

Science Daily  May 13, 2021
The test called RAPID developed by an international team of researchers (USA- U Penn, Brazil) uses electrochemical impedance spectroscopy (EIS), which transforms the binding event between the SARS-CoV-2 viral spike protein and its receptor in the human body into an electrical signal that clinicians and technicians can detect. The signal allows the test to discriminate between infected and healthy human samples. The signal can be read through a desktop instrument or a smartphone. In tests it has proved to be quick and reliable. The technology is affordable and scalable, electrodes used in the test can be quickly mass-produced using commercially available screen-printers to print the circuit board. It can be used to detect other viruses and diagnose a variety of diseases such as the flu or sexually transmitted diseases…read more. Open Access TECHNICAL ARTICLE
