A polymer microfluidic multiplexer

This paper reports on the development of a polymeric microfluidic multiplexer, which can be applied to perform a variety of functions involving liquid manipulation and control in microfluidics devices/systems, portable biosensors, and other miniaturized systems. The developed device was applied for 1times8 multiplexing of a test liquid, i.e., the test liquid was injected into the device through one inlet and injected out through eight similar outlets. It was also applied for the formation of micro-arrays of liquid drops on a surface. The device can be designed to deliver either a single or several different liquids.
