Abstract

A microfluidic device for conducting a fluid assay includes an injection-molded (or “molded”) fluidics layer having at least one microfluidic channel configured to allow assay fluids to flow there-along, the channel having channel side walls, a channel bottom, and a channel 3D geometry, and the fluidics layer being made from injection-molded liquid silicone (or PDMS). Having the fluidics layer made from injection molded liquid silicone enables smaller-sized channel features, such as microfluidic valves and pistons, smaller channel dimensions and spacing (providing smaller device footprint, higher device capacity and other benefits), and various geometries for the channels and channel features.
