A credit card-sized device that can spot infectious diseases

This video showcases a credit card-sized microfluidic device that can inexpensively identify infectious diseases such as HIV or syphilis in the developing world. The team's findings were reported (registration required) in Nature Medicine.

This is one of several interesting examples of new diagnostic technologies based on microfluidic chips. Earlier this year, Stanford's Stephen Quake, PhD, and Hannah Valantine, MD, developed a microfluidic assay to better detect heart transplant rejections.
