Abstract

Suspended microchannels have been created by utilizing sacrificial polymer fibers fabricated from solvated polymer solution with a novel direct-write technique. Characterization of this fiber drawing process has demonstrated correlation between solution concentration and fiber diameter, thereby proving a mechanism for controlling microchannel inner diameter. These hydrophilic microchannels, with diameters ranging from 4 to 100 Pm, were loaded with buffer solution and electroosmotic flow was induced.
