Microfluidic Chemical Concentration Switching at Taylor's Limit

ORAL

Abstract

In this talk, we will discuss the time for switching chemical concentrations in microfluidic devices. The limits of rapid switching are analyzed based on the theory of dispersion by Taylor and Aris and compared to both experiments and numerical simulations. We conclude by comparing the performance of various switching techniques.
