Provided are nucleic acid isolation unit and method. The method includes immobilizing an aromatic compound-containing nucleic acid intercalator on a solid support; contacting a first buffer solution containing a nucleic acid sample to be purified to the intercalator immobilized on the solid support to bind the intercalator with nucleic acids contained in the nucleic acid sample; cleaning the resultant structure where the nucleic acids are bound to the intercalator immobilized on the solid support; and eluting the nucleic acids with a second buffer solution.

Provided is a method of storing a substrate having an active group or a probe molecule immobilized thereon. The method includes attaching a UV film to a surface of the substrate having the active group or probe immobilized thereon; and exposing the UV film to UV light, wherein the UV film comprises a UV-permeable base film and a pressure sensitive adhesive layer formed on a surface of the UV-permeable base film to immobilize the substrate, and when the pressure sensitive adhesive layer is exposed to the UV light, its adhesive force decreases.
