Integration of Modeling in the Optimization
of Experimental Parameters in Microfluidics
and Capillary Electrophoresis
For several years we have focused and collaborated in applying chemometrics in the optimization of experimental parameters in CE and microfluidics. The heterogeneity of complex chemical and biological systems raises fundamental difficulties with regard to the ability of investigators to separate and detect analytes of interest, and to correlate variables and predict patterns within samples and differing sample matrices. Fortunately, the recent development of novel learning algorithms, hybrid computational techniques, and gains in raw computing power and speed, has raised several fundamental modeling and simulation research lines to account for these difficulties. We recently implemented the use of hybrid neural network methodology in optimizing fluorescence upon binding a receptor to a ligand on a microchip. Previous work has applied experimental designbased techniques in flowinjection, affinity capillary electrophoresis (ACE) and electrophoretically mediated microanalysis (EMMA).
