    • The diffusion coefficient of the dyes was extrapolated from published values for smaller compounds (100-200 Da), assuming that the coefficient was inversely proportional to the cube root of the molecular weight of the solute (Tanford, C., Physical Chemistry of Macromolecules, 1961, John Wiley & Sons, New York). The formula weights of Yellow #6 and Blue #1 are 452 Da and 793 Da, respectively.

    • Although light transmittance is a non-linear indicator of dye concentration, it is an excellent indicator of the uniformity of the concentration field. Admittedly, the photographs show only horizontal concentration gradients and do not reveal vertical gradients. It is possible for a serpentine channel to redistribute two incoming streams in a manner that maintains vertical gradients while appearing uniform from the top (uniform flow layering). However, Fig. 5 and Fig. 6 indicate that the flow layering in our flat serpentine mixers is not uniform. The twists leave an unlayered region along the lateral edge of each channel, where we have observed the highest (or lowest) concentration to be. Therefore, we consider that a uniform dye appearance does indicate sufficient mixing for our application. More accurate measures of mixing can be made by confocal micrsocopy (e.g., ref 32) or fluorescence techniques (e.g., M. S. Munson and P. Yager, Anal. Chim. Acta, 2004, 507, 63-71.
