Quantitative Spatial Mapping of Mixing in Microfluidic Systems

Abstract

The problem of miniaturizing the mixing process is a barrier to the advance of microfluidic technology. Fluorescence lifetime imaging is a powerful technique for the quantitative mapping of mixing in microfluidic systems, providing information essential to the design and evaluation of next-generation devices. With the use of a pulsed laser (B), mixing in a microfluidic cell (A) can be measured with fluorescence (C); a sample image is shown (right).
