Abstract:
A microfluidic system for diluting a material in a microfluidic device, the system comprising:a microfluidic device having at least a first main channel disposed therein, said main channel having at least one microscale cross-sectional dimension;at least a first source of said material in fluid communication with said main channel at a first point along a length of said main channel;at least a first diluent source in fluid communication with said main channel at a second point along said length of said main channel;at least a first reservoir in fluid communication with said main channel at a third point along said length of said main channel; anda fluid direction system for delivering diluent and material to said main channel, and combining said diluent with said material to form first diluted material, and for transporting a portion of said first diluted material along said main channel.
