First Claim
1. A cartridge, comprising:
- (a) a container comprising a plurality of closed and fluidically isolated chambers, wherein each of the plurality of chambers comprises a friable seal; and
(b) a microfluidic device engageably connected to the container, the microfluidic device comprising a fluidics layer, the fluidics layer comprising;
(i) a plurality of microfluidic channels; and
(ii) a plurality of puncturing elements, each of the plurality of puncturing elements protruding from the microfluidic device and disposed opposite the friable seal of one of the plurality of chambers and configured to puncture said friable seal, wherein each of the plurality of puncturing elements has an opening in fluidic communication with a microfluidic channel,wherein, upon engaging the microfluidic device with the container, the plurality of puncturing elements puncture the respective friable seals of the plurality of chambers and bring the plurality of microfluidic channels into fluidic communication with the plurality of chambers by means of the respective openings of the plurality of puncturing elements, thereby (1) creating a fluid flow path between a pair of chambers of said plurality of chambers of the container through a microfluidic channel of the microfluidic device and/or (2) creating a fluid flow path between a pair of microfluidic channels of the microfluidic device through one of said plurality of chambers of the container, andwherein, for each of the plurality of chambers, the microfluidic device has a corresponding first puncturing element disposed opposite a first portion of said chamber and a corresponding second puncturing element disposed opposite a second portion of said chamber such that, upon engaging the microfluidic device with the container, each first puncturing element punctures the friable seal at the first portion of said chamber and each second puncturing element punctures the friable seal at the second portion of said chamber and brings at least one of the plurality of microfluidic channels into fluidic communication with said chamber by means of the opening of the first puncturing element and the opening of the second puncturing element.

Abstract
This disclosure provides an integrated and automated sample-to-answer system that, starting from a sample comprising biological material, generates a genetic profile in less than two hours. In certain embodiments, the biological material is DNA and the genetic profile involves determining alleles at one or a plurality of loci (e.g., genetic loci) of a subject, for example, an STR (short tandem repeat) profile, for example as used in the CODIS system. The system can perform several operations, including (a) extraction and isolation of nucleic acid; (b) amplification of nucleotide sequences at selected loci (e.g., genetic loci); and (c) detection and analysis of amplification product. These operations can be carried out in a system that comprises several integrated modules, including an analyte preparation module; a detection and analysis module and a control module.
