Abstract
A method of forming a pneumatically controlled microfluidic device containing a micro-fluidic network that includes micro-elements in the form of micro-particles or micro-length hollow flow elements, and a pneumatic network that includes pneumatic micro-channels and micro-valve features enabling membrane valves to operate to control fluid conditions in the microfluidic network, including the steps (a) forming two portions, denominated fluidic layer, in which microfluidic channels are formed, and pneumatic layer, in which pneumatic micro-channels and micro-valve features are formed, each having a backing that is rigid in the plane of extent of the layers, (b) providing an intervening elastic membrane, and (c) permanently bonding both layers to opposite sides of the membrane, the permanent bonding of the membrane to the fluidic layer being effective to permanently enclose a set of inserted micro-elements in the fluidic network and relate the two layers to enable pneumatic control of fluid conditions in the microfluidic network.
