1. A method for making a mobile, monolithic polymer element in a microchannel, comprising;

  • a) injecting a monomer mixture dissolved in a solvent into the microchannel, wherein the composition of the monomer mixture is such that the polymer formed by polymerizing the monomer does not bond to the microchannel wall;

    b) polymerizing the monomer by application of radiation; and

    c) flushing unpolymerized monomer mixture from the microchannel.
