Method and device for biomolecule preparation and detection using magnetic array
09689842 · 2017-06-27 · ·

An embodiment of the invention relates to a device for detecting an analyte in a sample. The device comprises a fluidic network and an integrated circuitry component. The fluidic network comprises multiple zones such as a sample zone, a cleaning zone and a detection zone. The fluidic network contains a magnetic particle and/or a signal particle. A sample containing an analyte is introduced, and the analyte interacts with the magnetic particle and/or the signal particle through affinity agents. A microcoil array or a mechanically movable permanent magnet is functionally coupled to the fluidic network, which are activatable to generate a magnetic field within a portion of the fluidic network, and move the magnetic particle from the sample zone to the detection zone. A detection element is present which detects optical or electrical signals from the signal particle, thus indicating the presence of the analyte.

09649639 · 2017-05-16 · ·

A separation apparatus comprises a base defining a mounting surface with a length and a width. The separation apparatus further includes a pair of clamps configured for toolless operation. The pair of clamps are spaced apart from one another along the length of the mounting surface and configured to inhibit a movement of the sample plate relative to the mounting surface. In further examples, methods of separating a magnetic material within containment areas of a sample plate are provided including the step of clamping a first edge portion of the sample plate with the spring clip and clamping a second edge portion of the sample plate with a jaw mechanism. The method further includes the step of inverting the base together with the sample plate such that liquid drains from the containment areas while magnetic material remains in the containment areas under the influence of respective magnets.
