Engineering scientists at Stanford University have build an ultra-low cost human powered blood centrifuge separating blood into individual components in 1.5 minutes.
It is created from 20 cents of twine, paper and plastic and is called a paperfuge.
It can spin at speeds of 1,25,000 revolutions per minute and exert centrifugal forces of 30 thousand Gs.
It is the fastest spinning object driven by human power. It has the potential to enable precise diagnosis and treatment of diseases such as malaria, HIV and TB.
