Micro fluidic interface technology based on stereolithography for glass-based lab-on-A-chips

Abstract

As lab-on-A-chips are developed for on-chip integrated micro fluidic systems with multiple functions, the development of micro fluidic interface (MFI) technology to enable integration of complex micro fluidic systems becomes increasingly important and faces many technical difficulties. Such difficulties include the need for more complex structures, the possibility of biological or chemical cross-contamination between functional compartments, and the possible need for individual compartments fabricated from different substrate materials. This chapter introduces MFI technology, based on rapid stereolithography, for a glass-based miniaturized genetic sample preparation system, as an example of a complex lab-on-A-chip that could include functional elements such as; solid-phase DNA extraction, polymerase chain reaction, and capillary electrophoresis. To enable the integration of a complex lab-on-A-chip system in a single chip, MFI technology based on stereolithography provides a simple method for realizing complex arrangements of one-step plug-in micro fluidic interconnects, integrated microvalves for micro fluidic control, and optical windows for on-chip optical processes © Springer Science+Business Media, LLC 2013.
