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.
Claims20
A deoxyribonucleic acid (DNA) analysis device comprising:
- a substrate;
- a photosensitive organic layer configured to be disposed on the substrate and deformed by reacting to light;
- a pair of sensing electrodes disposed on the photosensitive organic layer and spaced apart from each other by a nano gap;
- and
- a light irradiation unit configured to irradiate the light to the photosensitive organic layer,
- wherein when the photosensitive organic layer is deformed, the nano gap between the pair of sensing electrodes is varied.
A device, comprising:
- a first tip electrode including a first nanowire;
- a second tip electrode including a second nanowire;
- a nano gap separating the first tip electrode from the second tip electrode;
- an insulating layer underlying the first tip electrode and the second tip electrode;
- a groove in the insulating layer, the groove overlapping the first and second tip electrodes;
- a photosensitive organic layer underlying the insulating layer;
- and
- a controller operable to cause polarized light to be directed onto the photosensitive organic layer while a deoxyribonucleic acid (DNA) strand passes through the nano gap.
A method, comprising:
- forming a photosensitive organic layer on a flexible substrate;
- forming an insulating layer on the photosensitive organic layer;
- forming a groove in the insulating layer;
- forming a nanowire on the insulating layer on either side of the groove and extending across the groove;
- and
- forming a pair of tip electrodes separated by a nano gap by passing an electrical current through the nanowire.
