Apparatus for analyte processing
The invention relates to a cartridge for processing a sample and methods for aligning a cartridge. The cartridge includes a processing device for processing a sample, a body having a surface and bounded by at least one edge, and a plurality of positioning members defined by the surface for aligning the processing device relative to a conduit defined by the body between a cartridge input and a cartridge output.
1. A cartridge for processing a sample, comprising:
a body having a first surface and a second surface on opposing faces of the body, the first surface of the body adapted to lay upon a support surface of a housing, the second surface of the body defining one or more cartridge positioning members configured to engage one or more socket positioning members of a socket of the housing;
a sample processing device including a sensor disposed on the second surface of the body of the cartridge, wherein the sample processing device defines a plurality of cavities through which the sample flows, each cavity having a surface defining a membrane sensitive to the flow of the sample;
a plurality of electrical contact pads located in a fixed relation to the one or more cartridge positioning members so that when the socket is spaced proximate to the second surface of the cartridge, the one or more cartridge positioning members engage with the one or more socket positioning members to align the plurality of electrical contact pads of the cartridge with a plurality of electrical contacts of the socket; and
the body of the cartridge defining a plurality of fluid conduits, each fluid conduit in fluid communication with a respective cavity of the sample processing device and through which the sample flows to the respective cavity of the sample processing device, each fluid conduit configured to align through the second surface of the body with a magnet of the socket.
2. The cartridge of claim 1 further comprising a plurality of sample inputs, each sample input in fluid communication with a respective fluid conduit.
3. The cartridge of claim 2 wherein each sample input includes a sample reservoir.
4. The cartridge of claim 1 wherein the cartridge defines a raised surface configured to engage the socket and prevent the magnets of the socket from contacting the sample processing device.
5. The cartridge of claim 1 wherein the plurality of cartridge positioning members comprise apertures defined by the surface of the body.
6. The cartridge of claim 1 wherein the plurality of cartridge positioning members comprise pins disposed on the surface of the body.
7. The cartridge of claim 1 wherein the sample processing device is a sensor for sensing the sample in the conduit.
8. The cartridge of claim 1 wherein the sample processing device is a flexural plate wave device.
9. The cartridge of claim 1 wherein the sample processing device is a silicon containing chip.
10. The cartridge of claim 1 further comprising an electrode cover sealing a surface of the sample processing device.
11. The cartridge of claim 1 further comprising a thermal transfer layer disposed on a portion of the first surface of body.
12. The cartridge of claim 1 further comprising a hydrophilic layer disposed on a portion of the first surface of body.
13. The cartridge of claim 1 wherein the sample processing device defines a membrane sensitive to a flow of the sample, wherein the membrane of the sample processing device is configured to form bonds with complexes comprising magnetic particles of the sample.
