Abstract
A DNA analyzer includes an interface for coupling a microfluidic chip to the DNA analyzer. The microfluidic chip includes a first separation channel for electrophoretic separation of DNA fragments in a first sample. Further, the DNA analyzer includes a first optical device. The first optical device includes an illuminating path and a detecting path. The illuminating path directs a first input light beam received from a light source to a first separation channel of the microfluidic chip. The first input light beam causes fluorescent labels attached on DNA fragments in the first separation channel to emit a first fluorescence light. The detecting path collects and directs the first fluorescent light to a first plurality of optical fibers. Further, the DNA analyzer includes a spectrometer configured to receive the first fluorescent light from the plurality of optical fibers and detect fluorescent components in the first fluorescent light.
