Abstract
An isolation device of target particles from a liquid sample includes an isolation chip, a vacuum unit, and a frequency converting unit. The isolation chip includes a sample reservoir, a first chamber, and a second chamber. The first chamber and the second chamber define a first outlet and a second outlet, respectively. The vacuum unit is connected to the first outlet and the second outlet. The frequency converting unit causes the vacuum unit to generate negative pressures in the first chamber and the second chamber alternately.
