1. An apparatus, comprising:
- a plurality of multi-lane microfluidic cartridges, each lane comprising a reaction zone;
a plurality of receiving bays, each receiving bay configured to receive one of the plurality of microfluidic cartridges;
each reaction zone comprising multiple separately controllable heaters thermally coupled thereto, the heaters configured to simultaneously and uniformly heat the reaction zone to carry out nucleic acid amplification on a polynucleotide-containing sample in the reaction zone;
a detector configured to detect the presence of an amplification product in one or more reaction zones; and
a processor coupled to the detector and the heaters, configured to control heating of one or more reaction zones by the heaters.

Abstract
The present technology provides for an apparatus for detecting polynucleotides in samples, particularly from biological samples. The technology more particularly relates to microfluidic systems that carry out PCR on nucleotides of interest within microfluidic channels, and detect those nucleotides. The apparatus includes a microfluidic cartridge that is configured to accept a plurality of samples, and which can carry out PCR on each sample individually, or a group of, or all of the plurality of samples simultaneously.
