Rapid On-Board Microfluidic Mixing Method Using Simple Pneumatically Actuated Diaphragm

ALine Inc.

Successful microfluidic products integrate robust components capable of complex functions while being tolerant to a range of conditions. Our proprietary microfabrication process, Integrative Polymeric Platform (IPP), is used to manufacture microfluidic devices with on-board, pneumatically actuated components that provide robust performance. On-chip active mixing by a simple bellows pump is studied in this paper by measuring the light absorption of a chemical reaction where fluid color changes when reagents combine. Successful demonstration of fast acting and low-variability performance of on-chip functions renders Integrative Polymeric Platform a reliable process for providing viable product solutions for complex disposable microfluidic devices.
