A rapid colorimetric paper-based sensor strip for point-of-care monitoring of the blood plasma coagulation.

Coagulation disorders can lead to dangerous bleeding or clot formation. Since centralized laboratories cannot provide rapid results for timely treatment intervention in patients with coagulation disorders, the existence of coagulation sensors for the general public is necessary. The purpose of the present research is to design and fabricate a novel, portable, low-cost, paper-based colorimetric sensor for measuring blood prothrombin time.
