Abstract:
1. A manifold structure comprising: a first substrate having a first surface, the first surface having an iniferter species attached to the surface; a second substrate having a first surface and a second surface, the second substrate having a plurality of access ports, each extending from the first surface to the second surface, the first surface having an iniferter species attached to the surface; a spacer between the first and second substrates such that the first and second substrates and the spacer define a cavity, the cavity partially defined by the first surface of the first substrate and the first surface of the second substrate; and polymerized polymer precursor disposed in the cavity, wherein the polymerized polymer precursor includes a monomeric species, a photoinitiator, and an iniferter species, wherein the polymerized polymer precursor defines at least one fluidic feature in fluid communication with at least one of the plurality of access ports, and wherein at least a portion of the polymerized polymer precursor defines a polymer surface having at least some of the iniferter species on the polymer surface; and wherein a first one of the plurality of access ports is configured to supply an unpolymerized polymer precursor solution to the cavity, at least one of the first and second substrates is sufficiently transparent to allow illumination of the cavity through the transparent substrate to polymerize a region of the unpolymerized polymer precursor in the cavity, and wherein a second one of the plurality of access ports is configured to remove partially polymerized polymer precursor solution from the cavity.
