That is a giant step. I watched the video and other than showing color in a nice pattern it did little to explain how the chip works. I think the subset of the MEMS maybe generating a magnetic field which works to polarize the molecules in the blood sample to separate. Thereby acting as a filter for the blood. I'm not sure how it can filter out the DNA to a point where one can identify the markers. In the lab, they use reagents to chemically separate the bonds and they use filters to eliminate the unwanted molecules. This method appears to be using magnetic fields to do the bond breaking. Thank you for the post, it was very thought provoking.
