The blood-brain barrier on a chip is as small as many organs on chips, but it gives astrocytes lots of room to unfold in 3D. Credit: Georgia Tech / YongTae Kim lab

In the new blood-brain barrier on a chip, astrocytes (bottom) grow more naturally and function better. They interface with epithelial cells above them, and the better astrocyte health helps the rest of the culture function better, too. Credit: Georgia Tech / Kim lab / Yonsei University College of Medicine

Georgia Tech biomedical engineering researcher YongTae "Tony" Kim led the development of the blood-brain-barrier on a chip. Here, be is holding up a microfluidic device that mimics a microvessel from other research. Kim is the recipient of the esteemed NIH Director's New Innovator Award for his proposal on high-throughput research to tackle new possible new treatments for atherosclerosis. Kim is also developing a human-coronary-artery-on-a-chip. Credit: Georgia Tech / Christopher Moore
