A sensor using electrophoresis may include a microfluidic channel and electrodes on opposite sides of the microfluidic channel that generate an electric field across the channel or perpendicular to the channel. The electric field can be used to move charged particles of matter, particularly those suspended in the fluid in the microfluidic channel, toward one of the electrodes or away from one of the electrodes. The electric field can be adjusted to allow the substance to continue to flow through the microfluidic path, remove non-target substances, or take measurements of other target substances. |
