This technique is rumoured to be fast and accurate in the early detection of malaria.
Scientists have used magnetic sensors to diagnose malaria five times more accurately than established diagnostic techniques.
Until now scientists have only tested infections in mice but, if the technique is confirmed in humans, doctors could diagnose the disease two to four days earlier, providing the crucial extra time to administer life-saving medicine.
The new method, reported in Nature Medicine (31 August), exploits the inherent magnetism of the iron in red blood cells. Read more: http://www.sciencealert.com.au/news/20140609-26137.html
