A Stanford researcher has created a groundbreaking scientific device using paper and string. It’s called a paperfuge and it may be the answer to testing blood samples in places that can’t power, afford, or transport a traditional centrifuge.
The device can attain speeds of 125,000 RPM and “can separate pure plasma from whole blood in less than 1.5 min, and isolate malaria parasites in 15 min,” the team says in the paper.
The Paperfuge works the same as a traditional centrifuge, separating the contents of biological samples like blood and plasma, through rapid spinning.
And that spinning is the first step toward diagnosing dangerous illnesses like malaria and HIV.The researchers tested the device and used it to isolate malaria parasites from blood in 15 minutes.
