(A) Design and characterization of dolomite micromixer-based chip. The micrographs with colored dyes show the flow and mixing pattern in various locations of the derivatization channel. Panel (B) shows segregated flow streams, whereas (A) demonstrates a uniform color pattern indicating mixing. The micrographs (C, D) demonstrate the fluorescence in the derivatization channels with 1 mM Asp, 7 mM NDA in ACN, and 10 mM NaCN in 50 mM borate buffer at pH 9.2.
