Improving disease detection with a little heat

In many parts of the world where tuberculosis is endemic, medical resources, such as laboratory equipment, are sometimes scarce. So analytical chemists want to develop simple, low-cost diagnostic tests for the disease. To help detect dilute biomarkers for tuberculosis in urine, researchers now report an inexpensive method that increases a biomarker’s concentration on a strip of paper (Anal. Chem. 2014, DOI: 10.1021/ac503751a).
