Provided is a method of manufacturing a coil unit in a thin film type for a compact actuator, and more particularly, a method of manufacturing a coil unit in a thin film type for a compact actuator in which a buffer layer is formed on a coil layer to prevent cracks in the coil layer and a substrate.

According to the method of manufacturing the coil unit in a thin film type for a compact actuator of the present invention, the buffer layer is formed on the coil layer so that an impact to the coil layer during a back-grinding process for thinning a substrate is absorbed, thereby preventing the substrate and the coil layer from breaking due to the back-grinding process and compensating for a difference of deformation between the coil unit and the substrate according to a difference of coefficients of thermal expansion.

Further, according to the present invention, as the substrate is thinned by performing a back-grinding process, a gap which is a distance between a permanent magnet and the coil layer is reduced, and therefore sensitivity of the compact actuator can be improved.

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.
