Malaria in humans is caused by Plasmodium parasites that infect red blood cells. Nearly half of the world’s population is at risk of malaria. Despite around 212 million cases of malaria reported in 2015, deaths from the disease have dropped dramatically since 2010. This is partly due to improved diagnostics, allowing swift treatment. In severe infections it is possible to see the parasites in a blood sample using a microscope, but more sensitive tests are needed to diagnose all infections.
#BloodDiamond explores two new reseach techniques for detecting malaria: acoustic levitation and attenuated total reflection (ATR) sampling in conjunction with infrared spectroscopy. Acoustic levitation uses sound to levitate a single drop of blood and ATR uses a diamond to reflect an infrared beam of light through a blood sample to detect malaria parasites.
A large single red blood cell levitates and glows as the visitor enters the exhibition room. This is a healthy blood cell. Using an infrared camera or augmented reality Hololens headset, Plasmodium infected blood cells can be detected within the space, each identifiable by distinctive changes in cell morphology.
