Abstract

The need for rapid, cheap and accessible method to accurately quantify the rheological state of a clotting sample of blood has been highlighted by the recent COVID-19 pandemic. Such a device would be significant for use for theranostic application in trauma care and warfarin clinics. Extensive resea...
