Abstract

A method for efficiently manufacturing and fabricating microfluidic chips, where a base mold is formed to have positive-relief features used to cast an intermediary template chip with negative-relief features having dimensions of a scale in the micron range. The intermediary template chip is used to case a production mold, which is formed of a reinforced epoxy resin that, once hardened into a solid epoxy member, can withstand the structural pressures of a CNC machining system. The production mold can be refined by a CNC machining, where the refined production mold is then used to cast production chips to be used as microfluidic chips.
