摘要： Micro-fluid devices and methods for their use are provided. The subject devices are characterized by the presence of at least one micro-valve comprising a phase reversible material, e.g. a reversible gel, that reversibly changes its physical state in response to an applied stimulus, e.g. a thermoreversible gel. In using the subject device, fluid flow along a flow path of the device is modulated by applying an appropriate stimulus, e.g. changing the temperature, to the microvalve. The subject devices find use in a variety of applications, including micro-analytical applications.

摘要： Methods for selectively separating at least one component from a multi-component componant fluidic sample are provided. In the subject methods, the fluidic sample is introduced into a micro-fluidic device that includes at least one micro-valve made up of a phase reversible material. The multi-component fluidic sample is then contacted with the microvalve in a microfluidic device under conditions sufficient for the at least one component to enter the microvalve, while the remaining constituents of the fluidic sample remain outside of the microvalve. Also provided are kits for use in practicing the subject methods, where the kits include at least a microfluidic device having a microvalve and instructional material (or means for obtaining the same) on how to use the device in the subject methods. The subject devices find use in a variety of applications, including sample desalting and concentration applications.
