Limitation for electrically driven technique.

	Channel size (μm)	Suitable for electrically driven	Equivalent electric resistance	Alternative
Conventional electrophoresis	500–3000 or more	Fit, lower efficiency	Small	Syringe pump, etc.
Capillary electrophoresis, lab-on-chip, etc.	50–500	Fit, high efficiency	Middle	Electrically driven pump
Single macromolecule analysis	1–50	Fit, lower efficiency	Large	Light-driven, etc.
Nanochannel research	0.001–1	Unfit	Huge	—
