Abstract:
A method of serially transporting a plurality of test compound plugs in a microfluidic channel, comprising:providing a microfluidic channel having a smallest cross-sectional dimension that is less than a maximum dimension d, where: ##EQU24## introducing a first test compound plug, where P is a period of time required to introduce the test compound plug into the channel, D is the diffusion coefficient of the test compound in the test compound plug, K is a proportionality factor, T is an amount of time for the test compound plug to move from introduction into the channel to a point of detection, and n is a ratio of initial plug length to average dispersion distance for the test compound in the test compound plug in time T, provided that T is greater than P; andintroducing a second test compound plug into the channel after the first test compound plug.
