Abstract
A sequencing apparatus may include a bio-disk having reaction regions in which nucleic acids are polymerized; a stage configured to revolve around an axis, the stage including optical heads for detecting lights emitted from the plurality of reaction regions due to the polymerization of the nucleic acids; and/or a control unit configured to generate data regarding base sequences of the nucleic acids in the reaction regions based on wavelengths of the lights detected by the plurality of optical heads. An optical head may include a light emitting unit configured to emit light toward a reaction region in which nucleic acids are polymerized; a light receiving unit configured to receive the light emitted by the light emitting unit; a de-multiplexing unit configured to de-multiplex the light received by the light receiving unit; and/or a plurality of photoelectric converting units configured to convert the de-multiplexed light to electrical signals.
