Device and method for particle complex handling
First Claim
1. A method comprising providing a device comprising an integrated circuitry component and a fluidic network comprising a magnetic particle in a fluid, generating a magnetic field that interacts with the fluidic network, and transporting the magnetic particle by the magnetic field that interacts with the fluidic network without fluidic movement of the fluid in the fluidic network, wherein generating the magnetic field that interacts with the fluidic network is by programmably activating magnetic microcoils in a vicinity of the fluidic network.

Abstract
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 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.
