Abstract: According to an aspect of the present disclosure, a DNA analysis device includes a substrate; a photosensitive organic layer configured to be disposed on the substrate, and expanded or contracted by reacting to light; a pair of sensing electrodes disposed on the photosensitive organic layer, and spaced apart from each other with a nano gap; and a light irradiation unit configured to irradiate the light to the photosensitive organic layer, and when the photosensitive organic layer is deformed, the nano gap between the pair of sensing electrodes is varied. Accordingly, the nano gap is simply and precisely adjusted by using the photosensitive organic layer which reacts to light to enhance DNA analysis accuracy.
