Abstract
A device comprising a channel comprising at least one surface wherein the surface comprises a fluid-impervious base surface covered by a coating beginning at a proximal location and ending at a distal location along the at least one surface of the channel, the coating forming a surface energy gradient from the proximal location to the distal location on the surface, wherein the coating comprises a species having a functional group M1 and a species having a functional group M2 where M1 and M2 have different surface energies, wherein the functional group M2 comprises an amide or amine group, and the concentration of the species comprising functional group M2 in the coating increases relative to the concentration of the species comprising functional group M1 from the proximal location to the distal location on the surface.
