Abstract

Nucleic acid extraction and purification cartridges and systems are provided. The cartridges can be removable and are configured to allow for the concentration of particles of interest, followed by nucleic acid extraction and purification. The cartridges directly contact samples and provide a partial barrier between samples and the reusable components of the system, thereby reducing the probability of clogging the system's microfluidics and fouling the lines, valves, and pumps of the system. Furthermore, these cartridges are designed to purity nucleic acids by removing the majority of inhibitors for down-stream genetic testing. Embodiments may comprise one, two, or three or more channels. In an exemplary embodiment the nucleic acid extraction and purification cartridge comprises a first channel containing a filter disposed therein; and a second channel containing a nucleic acid binding matrix disposed therein, wherein a first end of the cartridge is configured to directly contact a sample comprising a biological material, and wherein a second end of the cartridge Is configured to connect in a reversible fashion to a flow-through automated Instrument that controls fluid flow through the cartridge.
