An electrically controlled microfluidic system (1300) is provided including: providing a probe fluid (128) extending longitudinally; restricting a longitudinal movement of the probe fluid (128) by capillary effects; moving the probe fluid (128) longitudinally using an electric field, an electric field gradient, or a combination thereof; reacting a fluid under test (130) with the probe fluid (128) to start a reacting mixture; and measuring the reacting mixture over distance, time, or a combination thereof.
