Digital Microfluidic Biochips: From Manipulating Droplets to A Cyberphysical System for Quantitative Gene-Expression Analysis

 

Abstract:

Advances in microfluidics have led to the emergence of biochips for automating laboratory procedures in molecular biology. These devices enable the precise control of nanoliter volumes of biochemical samples and reagents. As a result, non-traditional biomedical applications and markets (e.g., high-throughout DNA sequencing, portable and point-of-care clinical diagnostics, protein crystallization for drug discovery), and fundamentally new uses are opening up for ICs and systems.

This lecture will first introduce electrowetting-based digital microfludic biochips and provide an overview of market drivers such as immunoassays and DNA sequencing. The audience will next learn about design automation and reconfiguration aspects of microfluidic biochips. Synthesis tools will be described to map assay protocols from the lab bench to a droplet-based microfluidic platform and generate an optimized schedule of bioassay operations, the binding of assay operations to functional units, and the layout and droplet-flow paths for the biochip. The role of the digital microfluidic platform as a “programmable and reconfigurable processor” for biochemical applications will be highlighted. The speaker will describe dynamic adaptation of bioassays through cyberphysical system integration and sensor-driven on-chip error recovery.

Finally, the speaker will highlight recent advances in utilizing cyberphysical integration for quantitative gene-expression analysis. This framework is based on a real-time resource-allocation algorithm that responds promptly to decisions about the protocol flow received from a firmware layer. Results will be presented on how this adaptive framework efficiently utilizes on-chip resources to reduce time-to-result without sacrificing the chip’s lifetime.
