Description
Summary: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. A novel chip design has been developed for performing pinched injections using a single power supply. This geometry minimizes injection time, and produces a focused sample plug in the central channel.
