DNA to go: Texas A&M chemical engineer aims for DNA lab-on-a-chip When Dr. Victor Ugaz talks about "catch-and-release," he means DNA, not fish. DNA is known to most of us these days through crime shows, but crime scene investigators and police detectives aren't the only ones who use DNA analysis. DNA identification is also used to diagnose diseases or detect biological agents and toxins. Ugaz, an assistant professor in the Artie McFerrin Department of Chemical Engineering at Texas A&M University, is working to miniaturize a sprawling DNA lab so that components needed for DNA analysis are available in a tiny lab-on-a-chip about the size of a business card.
