  • Particle focusing apparatus and method for focusing particles by using the same
    Patent number: 8142631
    Abstract: In a particle focusing apparatus and a method for focusing particles, the particle focusing apparatus includes a channel, a fixing member, a fluid feeding portion and a power supply. The channel has first and second ends and extends substantially in a line. The fixing member includes a first fixing portion connected to and fixing the first end, and a second fixing portion connected to and fixing the second end. The fluid feeding portion feeds fluid having particles into the channel. The power supply has first and second terminals. The first terminal passes through the first fixing portion and is electrically connected to an anode of the power supply. The second terminal passes through the second fixing portion and is electrically connected to a cathode of the power supply. Thus, particles fed into the channel may be more easily and efficiently focused to a central region inside the channel.

  • METHOD OF TRACKING SWIMMING PATH OF BACTERIUM
    Publication number: 20070281331
    Abstract: Provided is a method of tracking a swimming path of a bacterium which can exactly track the swimming path of the bacterium by modeling the bacterium as ellipsoidal in shape based on an image of the bacterium obtained while the ellipsoidal bacterium swims near a solid surface.
