Link: Cheap, portable diagnosis of disease

Researchers at Vanderbilt University have developed a quick and simple process of extracting disease markers from blood samples to run through a diagnostic chip. He says that in many developing countries people often go to hospitals just to check if they are sick and take away from real patients, and that this quick diagnosis can be used in the remote towns to save the hospitals time. 

Similarly, I was talking to Dr. Chen of the University of Florida the other day, and he was describing the importance of this kind of miniaturization of medical technology. In particular, how mass spectrometers have approached the level of portability that they can be used to identify specific bacterial presence on skin, which helps to diagnose infections. Though still expensive ($200,000 for one) they could soon be used in remote hotspots.
