Project: "Coffee Ring Stain" Diagnostics for Malaria
Drs. Wright and Haselton of Vanderbilt University in the U.S. will develop a new low-cost diagnostic tool in which a droplet of malaria-infected blood deposited on a glass slide will, based on fluid dynamics, leave a ring-like pattern as the blood evaporates. The slide will be prepared with a solution that will interact with a particular protein of the malaria parasite to visualize this "coffee ring stain," allowing for easy interpretation and ready diagnosis.
