Charles Mace of Tufts University in the U.S. will develop paper-based cards to improve the collection, storage, and transport of blood samples from remote areas to diagnostic laboratories in low-resource settings. Dried blood spot cards are a low-cost and simple method for collecting and storing blood samples for analysis. However, they have a very basic design, which makes it difficult to control sample volume and elute specific types of molecules, which are needed to properly perform many diagnostic tests.
