File this under the Totally Cool category: Researchers at Sandia National Laboratories have developed a new way to mix tiny volumes. Researchers use microfluidic devices for testing in bio labs and as micro-reactions cells for chemical sensing and fluid analysis. Microfluids often must be mixed, but scientists have lacked a simple and reliable way to do it.
Enter Sandia researcher Jim Martin and his colleagues, who have developed a new way to mix tiny volumes. Martin calls the approach vortex field mixing. To see a brief YouTube video demonstration and interview, visit: http://www.youtube.com/watch?v=_2izq-XOvlg
