Automating sample processing at low cost

What can be done with capillary-driven microfluidic devices? You can make laboratory tests portable and cheap – cheap enough to run just a few in any setting. An example that most people recognize is the home pregnancy test, which wicks urine through several test regions to produce a visible color change. That venerable technology is limited, however, and we think it can be pushed forward with an assortment of new methods.

Here we present several applications for the new methods being developed by us and others. Some propose processes that use staged reagent delivery to conduct a sophisticated chemical process, like signal amplification. Others bring together flows from multiple inlets to mix fluids, such as in a dilution circuit. Some, like the T-sensor, could use controlled diffusion of molecules between parallel flow streams to detect molecules of interest.

Explore the links below for a few examples of applications that leverage the strengths of capillary-driven microfluidic networks.
