    Abstract: A microfluidic product utilizing gradient surface energy coatings for fluid control comprising a plurality of fluid passages wherein at least one fluid passage comprises a coating configured to control liquid flow wherein the coating configured to control liquid flow comprises a gradient surface energy coating from a proximal location to a distal location on a surface of the fluid passage. The product can include uniform regions and surface gradient regions in the same passage. Coating compositions and product dimensions can be selected to provide control over different flow properties including fluid velocity, reduction and acceleration of fluid flow, and starting and stopping fluid flow.
