Abstract

This paper presents generation of either statically spatial or dynamically temporal logarithmic concentration in the same microfluidic device. We propose a serial dilution principle by controlling the flow pattern at each branching point via designing the flow resistance of microchannels. Simple and linear ratio of the flow resistance results in desired logarithmic concentration at outlets. Dynamically controllable logarithmic concentration is feasible as well by integrating valves in the microfluidic device. Applications include fast dose-response experiments and cellular analysis under rapid change of logarithmic concentration.
