Embodiment Construction

[0029] A simple microfluidic system for performing interfacial reactions may include at least one pump in fluid communication with a tube. Preferably, the tube is substantially cylindrical. A first fluid is injected into the tube such that its flow is stratified and continuous. Preferably, the Reynolds number of the first fluid is <2500, and more preferably <1000. A second fluid is injected into the tube, into the flow or flow of the first fluid. Preferably, the second fluid is injected in discrete quantities. In some embodiments, the first fluid is first injected with a continuous stratified flow such that the second fluid is injected directly into the flow of the first fluid. In other embodiments, discrete amounts of the second fluid are first introduced into the channel, and then the first fluid is injected such that it forms a substantially laminar fluid flow region around the discrete amounts of the second fluid. After the two fluids come into contact, a reaction occu...

Abstract

A microfluidic system for performing interfacial reactions can comprise at least one pump in fluid communication with a tube. A first fluid is injected into the tube so that its flow is laminar and continuous. A second fluid is injected in discrete amounts into the tube into the stream or flow of the first fluid. In other embodiments, discrete amounts of the second fluid are introduced into the channel first, then the first fluid is injected so that it creates a region of substantially laminar fluid flow around the discrete amounts of the second fluid. After the two fluids are in contact, a reaction occurs. The system can be configured so that the second fluid solidifies to form a capsule around the first fluid or vice versa. Other interfacial reactions also can be accomplished using the disclosed microfluidic systems and methods.
