Abstract:
1. A biomolecule detector, comprising: a biomolecule chip having a substrate, the substrate including a single slit which comprises at least one inner sidewall and forms an aperture in the substrate; biomolecules immobilized on the portions of the at least one inner sidewall forming opposing portions of the single slit; a light source configured to direct incident light perpendicularly to the single slit toward the biomolecule chip thus to pass through the single slit; a screen onto which an image of the biomolecules directly formed by a diffraction of a portion of the incident light passing through the single slit from the light source is projected and formed; and an analysis system connected to the screen, the analysis system being configured to calculate a position of the projected image of the biomolecules on the screen and configured to further calculate a refraction index and a destructive and/or constructive interference by a diffraction of the light passing through the single slit when the immobilized biomolecule are transparent.
