Abstract:
An illumination unit includes a plurality of light source units to emit light beams having different wavelengths, and a synthesizing prism to synthesize the light beams emitted from the light source units to proceed on the same path. The synthesizing prism includes a first triangular prism having a first outer surface to transmit or reflect the light beams according to a direction in which the light beams are input, and first and second boundary surfaces, a second triangular prism having a second outer surface to transmit the light beams, a third boundary surface arranged to face the second boundary surface, and a fourth boundary surface, a third triangular prism having a third outer surface to transmit or reflect the light beams according to a direction in which the light beams are input, a fifth boundary surface arranged to face the fourth boundary surface, and a sixth boundary surface arranged to face the first boundary surface, and a color separation portion arranged at least one of positions between the second boundary surface and the third boundary surface, the fourth boundary surface and the fifth boundary surface, and the sixth boundary surface and the first boundary surface, to selectively transmit or reflect the light beams according to a wavelength of each light beam.
Abstract:
The present invention provides a nucleic acid detector for detecting a base sequences of a target DNA of interest, which comprises a DNA chip in which probe DNA and electrochemiluminescent material such as tris(2,2′-bipyridyl) metal complex, or derivatives thereof are immobilized on a surface of gold electrode; an electrochemical apparatus for applying a predetermined voltage to the DNA chip with respect to a reference electrode; and an optical measurement apparatus for measuring electrochemiluminescence generated from the DNA chip. The present invention also provides a method for producing the said detector for nucleic acids, and method for detecting nucleic acids using the same in a cost-saving way with high sensitivity.
