One aspect of the present disclosure relates to a device for detecting a target analyte in a liquid sample. The device can comprise a housing. The housing can include an inlet for receiving a liquid sample, an outlet for removing a volume of the liquid sample from the device, a filter associated with the outlet and being sized and dimensioned to retain a target analyte on a surface thereof, and a flow system comprising at least one channel that is in communication with the inlet and the outlet. At least a portion of the at least one channel can be located substantially adjacent the surface of the filter and be shaped and dimensioned to reduce the amount of unreacted fluorescent probe available to create the background interference during detection of the target analyte.

Methods and systems are provided for isolating fetal cells from a maternal blood supply in order to perform non-invasive prenatal testing. In one example, a system for non-invasive prenatal testing includes a substrate coated with a cell-capturing surface, the cell-capturing surface including an array of pillar-like structures, each pillar-like structure including a plurality of intersecting arms.

The present invention relates to fluidic devices for preparing, processing, storing, preserving, and/or analyzing samples. In particular, the devices and related systems and methods allow for preservation or storage of samples (e.g., biospecimen samples) by using one or more of a bridge, a membrane, and/or a desiccant.

A cartridge for sample preparation includes an inlet configured to receive a collected sample, a phase transfer assembly including a plurality of bead layers, and an outlet. The collected sample is configured to be transferred through the bead layers of the phase transfer assembly to extract a compound therefrom. The outlet is configured to transfer the extracted compound to a detector for analysis of the extracted compound.

Described is a rotary valve that includes a stator, a rotor and a plurality of sample channels. The stator includes a stator surface having an inlet port, an outlet port and a plurality of selectable ports. The rotor includes a rotor surface having a first rotor channel and a second rotor channel. The rotor is configurable in a plurality of rotor positions, each of which couples the inlet port to one of the selectable ports through the first rotor channel and couples the outlet port to another one of the selectable ports through the second rotor channel. The two selectable ports are coupled to each other through one of the sample channels. The rotor has a bypass state defined by a rotor position, or angular range of rotor positions, at which the inlet port is coupled to the outlet port through the second rotor channel.

A cartridge reader controlled by processing means for carrying out a diagnostic test on a sample contained in a fluidic cartridge comprises a mechanical valve for isolating the sample with the cartridge. A system for actuating the mechanical valve comprises an actuation member configured to move the mechanical valve from an open position to a closed position and an armature connected to the actuation member. The armature is configured to engage an electromagnet, wherein the electromagnet can be switched between an active state in which it electromagnetically holds the armature and an inactive state in which it does not electromagnetically hold the armature. First biasing means arc disposed between the actuation member and a bearing surface, wherein the first biasing means is configured to bias the actuation member into a first position in which it actuates a mechanical valve in a fluidic cartridge inserted into the reader.
