Biochip including carbon nanotubes and method for sample separation using the same

A method of separating a target substance from a sample comprising:

• loading a sample on a sample loading portion of a substrate of a biochip;
• flowing the sample through a channel of the substrate, wherein the channel comprises a plurality of carbon nanotubes arrayed in intervals;
• and
• separating the target substance from the sample.

A method of separating a target substance from a sample comprising;

• disposing a plurality of carbon nanotubes in a channel of a substrate, wherein the carbon nanotubes are arrayed in intervals;
• loading a sample in the channel;
• flowing the sample through the channel;
• and
• separating the target substance from the sample.

A method of making a biochip comprising:

• disposing a metal layer on a substrate;
• oxidizing the metal layer to form a channel;
• and
• disposing a plurality of carbon nanotubes in the channel, such that the plurality of carbon nanotubes are arrayed in intervals.
