(57) [Problem] To provide a method for separating a target substance contained in a biochip and a sample in the biochip. SOLUTION: The substrate, a sample loading portion located on the substrate, a channel formed on the substrate and through which a fluid flows from the sample loading portion, and arranged at predetermined intervals in the channel. Loading a biochip including a plurality of carbon nanotubes, and a sample including a target material into a sample loading unit, passing the sample through a channel, and including the sample according to an arrangement interval of the carbon nanotubes. The method includes a step of selectively separating a target material. Various samples can be easily filtered or separated by the channels and chambers, and contamination of the samples and errors in the experimental results can be prevented. |
