Silicon-based Microdialysis Chip with Integrated Fraction Collection
G. L. Subrebost and G. Fedder
A silicon-based microdialysis chip that integrates sample acquisition and fractionation is demonstrated in this paper. A porous cellulose acetate film, created using the phase separation process, is suspended over silicon microchannels. Microfluidic fractionation is accomplished with passive microfluidic valves that are used to direct the dialysate into microfabricated collection chambers.
