This post has been changed due to an update to the Technology Review article.
Technology Review focuses its attention on RainDance Technologies' droplet-based microfluidics system, saying it "can be adapted to perform a number of chemical analyses." The company itself, though, is not developing its own genetic diagnostics, Tech Review says, but is selling its technology to labs that do. Emory's Madhuri Hegde is using the technology to develop a test for an X-linked form of mental retardation that looks at 93 different genes. "I think [the RainDance technology] holds lots of promise in a clinical setting," Hegde says, though she notes that it is expensive.
