    摘要： A method of forming a polymer-based microfluidic system platform using network building blocks selected from a set of interconnectable network building blocks, such as wire, pins, blocks, and interconnects. The selected building blocks are interconnectably assembled and fixedly positioned in precise positions in a mold cavity of a mold frame to construct a three-dimensional model construction of a microfluidic flow path network preferably having meso-scale dimensions. A hardenable liquid, such as poly (dimethylsiloxane) is then introduced into the mold cavity and hardened to form a platform structure as well as to mold the microfluidic flow path network having channels, reservoirs and ports. Pre-fabricated elbows, T's and other joints are used to interconnect various building block elements together. After hardening the liquid the building blocks are removed from the platform structure to make available the channels, cavities and ports within the platform structure. Microdevices may be embedded within the cast polymer-based platform, or bonded to the platform structure subsequent to molding, to create an integrated microfluidic system. In this manner, the new microfluidic platform is versatile and capable of quickly generating prototype systems, and could easily be adapted to a manufacturing setting.

    摘要： Various methods and devices are provided for delivering an infusion liquid using an electrokinetic infusion pump. The electrokinetic infusion pump can generally include an infusion housing having an infusion reservoir. The infusion reservoir has an infusion outlet and is capable of containing an infusion liquid. A plunger is movably coupled to the infusion housing and is adapted to be manually displaced relative to the infusion housing to load the infusion reservoir with infusion liquid. A movable partition can be disposed within the infusion housing and has a first surface in communication with an electrokinetic solution and a second surface, isolated from the first surface, in communication with the infusion reservoir. The electrokinetic infusion pump can further include an electrokinetic engine integrated within the plunger and adapted to selectively deliver electric potential across an electrokinetic porous media to cause the electrokinetic solution within the electrokinetic engine to displace the movable partition to effect delivery of at least a portion of the infusion liquid through the infusion outlet.
