Microfluidic Mixing of Reagents (VIDEO) University of Tokyo This video is under embargo. Please login to access this video. To view this video please enable JavaScript, and consider upgrading to a web browser that supports HTML5 video Caption By producing a large number of droplets containing different reagents in slightly different concentrations, it is possible to generate a high resolution map of how a reaction proceeds from different starting conditions. This video shows three reagents combined with pink, green and blue fluorescent markers flowing in from the bottom of the screen and mixing. At the top of the screen, the mixed solution passes through a tiny constriction to create droplets in an oil buffer. In the final experiment, the fluorescent markers are mixed with biochemical reagents, so recording the color concentration tells you how much of the reagent was injected in each droplet.
