At $0.20, ‘paperfuge’ is the cheapest and fastest hand-spun centrifuge ever designed — and can reach speeds up to 125,000 revolutions per minute. Made from cardboard, fishing wire and wood; 90 seconds of spinning is enough to separate a blood sample into red and white blood cells, platelets, and plasma.
A longer spin can separate the part of the blood needed for malaria testing. Nature Video reveals how this invention will allow basic diagnostic tests in areas without laboratory resources or electricity.
