This article reports on the research methodology for the development of a novel injection design for microfluidic systems that uses a single power supply to perform pinched injections.

Abstract

This work presents a novel injection design for microfluidic systems which is able to perform pinched injections using a single power supply. This geometry also minimizes the injection time compared to standard pinched injections. This new design was developed and investigated by computer simulation and these results were confirmed by experimental studies using the injection of fluorescent dye. (Published Abstract Provided)
