National Science Foundation: Chip delivers COVID-19 test results on a phone

National Science Foundation: Chip delivers COVID-19 test results on a phone. “COVID-19 can be diagnosed in 55 minutes or less with the help of programmed magnetic nanobeads and a diagnostic tool that plugs into an off-the-shelf cellphone, according to Rice University engineers. Mechanical engineer Peter Lillehoj has developed a stamp-sized microfluidic chip that measures the concentration of SARS-CoV-2 nucleocapsid (N) protein, a biomarker for COVID-19, in blood serum from a standard finger prick. The nanobeads bind to SARS-CoV-2 N protein in the chip and transport it to an electrochemical sensor that detects minute amounts of the biomarker.”
