TABLE I.

DEP motion of the microalgae with different lipid contents at the operating frequency between 5 and 20 MHz (solution conductivity: under 1.4 mS/cm).

Frequency	Lipid content (% dry wet)
21%	30%	35%
1 MHz	nDEP	nDEP	nDEP
2 MHz	pDEP	——a	nDEP
3 MHz	pDEP	pDEP	——

^a“——”means that the motion of the microalgae is less identifiable.
