A portable and low-cost diagnostic device has been developed by the researchers at Ecole Polytechnique Fédérale de Lausanne. This microfluidic tool, which has been tested with Ebola (lat. Zaire ebolavirus), requires no bulky equipment. It is thus ideally suited for use in remote regions. Over the past several years, microfluidic devices have shown extraordinary potential in the area of diagnostics. They are composed of silicone rubber with minuscule channels the width of a hair. Microfluidic devices, and can rapidly detect a number of different biomarkers in very small quantities of blood (lat. Sanguis).
