Electrokinetic pumping and detection of low-volume flows in nanochannels
Electrokinetic pumping of low‐volume rates was performed on‐chip in channels of small cross sectional area and height in the sub‐μm range. The flow was detected with the current monitoring technique by monitoring the change in resistance of the fluid in the channel upon the electroosmosis‐driven dis...

| description | Electrokinetic pumping of low‐volume rates was performed on‐chip in channels of small cross sectional area and height in the sub‐μm range. The flow was detected with the current monitoring technique by monitoring the change in resistance of the fluid in the channel upon the electroosmosis‐driven displacement of an electrolyte solution by a second electrolyte solution. Flow rates in the order of 0.1 pL/s were successfully generated and detected. The channels were fabricated with the sacrificial layer technology. |
