Abstract:
1. A method of mixing samples in-line in a microfluidic system, comprising: introducing a first fluid sample into a flow-tube at a first end at a given velocity via a first conduit; and intermittently introducing a second fluid sample into said flow-tube at said first end, via a second conduit, wherein said first fluid sample and said second fluid sample converge in said flow tube to form an interface; whereby said first fluid sample and said second fluid sample mix at said interface within said flow-tube, wherein fluid flow at said first end of said flow-tube is laminar and fluid flow at a second end of said flow-tube is laminar, and wherein said flow-tube has a constant diameter between said first end and said second end of said flow-tube.
