Provided is a method of isolating biochemical molecules on a microarray substrate, the method including providing a microarray substrate to which clusters of different kinds of biochemical molecules being classified by individual spot units are attached, the individual spots being regularly arranged thereon; obtaining location information of the individual spot in which a desired cluster among clusters of the biochemical molecules locates; locating an extraction tool for applying energy to isolate the desired cluster according to the location information; and isolating the desired cluster from the microarray substrate by applying energy in a contact or non-contact manner using the extraction tool.
