Bio-chip and method for separating and concentrating particles using the same

摘要

A bio-chip adapted for separating and concentrating particles in a solution includes a chip body defining a receiving space therein for receiving the solution, an inner electrode disposed in the receiving space, an outer electrode unit disposed in the receiving space of the chip body and including a first outer electrode that is spaced apart from and surrounds the inner electrode, and a second outer electrode that is spaced apart from and surrounds the first outer electrode, and a power source electrically connected to the inner electrode, the first outer electrode, and the second outer electrode. A method for using the bio-chip to separating and concentrating the particles in the solution is also disclosed in the present invention.

1. A bio-chip adapted for separating and concentrating particles in a solution, comprising:
a chip body defining a receiving space therein for receiving the solution; an inner electrode disposed in said receiving space of said chip body; and an outer electrode unit disposed in said receiving space of said chip body and including a first outer electrode that is spaced apart from and surrounds said inner electrode, and a second outer electrode that is spaced apart from and surrounds said first outer electrode, wherein said inner electrode, said first outer electrode, and said second outer electrode are concentrically disposed, and wherein each of said first and second outer electrodes has an outer periphery and an inner periphery to define a width therebetween, the width of said second outer electrode being greater than that of said first outer electrode.
