Bioactive Paper Towel Spells Your Blood Type In Seconds
Monash University researchers developed a prototype sensor on a piece of paper towel coated with water-resistant substance all over, except the areas showing four blood types and a positive or negative Rhesus factor. These areas are, packed with antibodies, interact with specific blood antigens that results in coagulation. One just has to rinse the coating to see the blood type spelled on the paper. Inspired by Harry Potter, and funded by Austrian Research Council (ARC) and a commercial partner, this device could save time and money if introduced to hospitals and emergencies.
