A biochip and a method for separating a target substance contained in a sample on the biochip are disclosed. The biochip comprises a substrate, a sample loading portion disposed on the substrate, a channel in fluid communication with the sample loading portion, and carbon nanotubes arrayed in intervals in the channel. The sample is loaded on the sample loading portion and flowed through the channel. The target substance is selectively separated from the sample according to the interval sizes between the carbon nanotubes. According to the present invention, various substances in a sample may be easily separated or filtered by flowing through the channel having the carbon nanotubes, and thus, sample contamination and/or experimental error are reduced.
