TABLE II.

DEP motion of the microalgae with different lipid contents at the operating frequency between 5 and 20 MHz (solution conductivity: 2.93 mS/cm).

Frequency	Lipid content (% dry wet)
13%	21%	24%	30%	35%
5 MHz	nDEP	nDEP	nDEP	nDEP	nDEP
10 MHz	——a	nDEP	nDEP	nDEP	nDEP
15 MHz	pDEP	pDEP	——	nDEP	nDEP
20 MHz	pDEP	pDEP	pDEP	nDEP	nDEP

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