Patent ID: 7601286

Claim:
A method of forming a microfluidic system platform comprising the steps of: providing a mold frame having frame walls surrounding a mold cavity; providing a set of independent mold forms for use in molding hollow microfluidic features, the set of independent mold forms comprising elongated mold forms for use in molding microfluidic channels, and block mold forms for use in molding microfluidic cavities; constructing a three-dimensional model construction of a microfluidic flow path network in the mold cavity by interconnecting mold forms selected from the set of independent mold forms and suspending the model construction in the mold cavity via the frame walls; introducing a hardenable liquid into the mold cavity to immerse the model construction thereby; hardening the liquid to form (1) a platform structure having a shape of the mold cavity and (2) the microfluidic flow path network in the platform structure having a seamless shape of the model construction and including at least two access ports for enabling fluidic communication with the formed microfluidic flow path network; and removing the model construction from the platform structure through the at least two access ports so as to avail the formed microfluidic flow path network.
