Applying Voltage to a Channel in a Microfluidic Chip

LabSmith application note December 26, 2012

Platinum wire electrodes are commonly used to apply voltage to a fluidic channel. Although the approach is relatively simple, proper preparation of the electrode is very important to prevent field concentrations in the channels. Field concentrations can cause a multitude of problems, including bubble formation, cell lysing, localized heating, chemical reactions, and clogging of channels.
