Autonomous Microfluidic Components, Circuits and Systems

Similar to the way in which integrated circuits (ICs) revolutionized electronics, the advent of integrated microfluidic circuitry could significantly impact both chemical and biological fields. Here we utilize fluidic techniques routed in mechanical engineering to develop next-generation microfluidic components and systems that are capable of autonomous “on-chip” functionalities.

Continuous Flow Particulate-Based Microfluidic Reactors

The ability to perform “multi-stage” fluidic mixing operations with suspended particles, such as living cells and micro/nanobeads, is a critical requirement for diverse chemical and biological applications. In our lab, we combine hydrodynamic railing and arraying techniques to passively execute multi-step particulate-based fluidic reaction processes, while enabling optical detection during each fluidic mixing stage.
