    Abstract: Integrated devices that include a sample preparation component integrated with a detection component are disclosed. The sample preparation component may be a digital microfluidics module or a surface acoustic wave module which modules are used for combing a sample droplet with a reagent droplet and for performing additional sample preparation step leading to a droplet that contains beads/particles/labels that indicate presence or absence of an analyte of interest in the sample. The beads/particles/labels may be detected by moving the droplet to the detection component of the device, which detection component includes an array of wells. Additonal analyte detection devices configured to operate an analyte detection chip to prepare a test sample and to detect an analyte related signal from the prepared test sample in the analyte detection chip are disclosed. The analyte detection chip may include a digital microfluidics (DMF) region and an analyte detection region which may overlap or may be spatially separated. The analyte detection device may be configured for detection of analyte by an optical or electrochemical means operably connected with an analyte detection chip inserted into the device.

    Abstract: Methods, devices, and systems for analyte analysis using a nanopore are disclosed. The methods, devices, and systems utilize a first and a second binding member that each specifically bind to an analyte in a biological sample. The method further includes detecting and/or counting a cleavable tag attached to the second binding member and correlating the presence and/or the number of tags to presence and/or concentration of the analyte. Certain aspects of the methods do not involve a tag, rather the second binding member may be directly detected/quantitated. The detecting and/or counting may be performed by translocating the tag/second binding member through a nanopore. Devices and systems that are programmed to carry out the disclosed methods are also provided. Also provided herein are instruments that are programmed to operate a cartridge that includes an array of electrodes for actuating a droplet and further includes an electrochemical species sensing region. The instrument may be used to analyse a sample in a cartridge that includes an array of electrodes for actuating a droplet and further includes a nanopore layer for detecting translocation of a tag/second binding member through nanopore. An instrument configured to operate a first cartridge that includes an array of electrodes for actuating a droplet and further includes an electrochemical species sensing region and a second cartridge that includes an array of electrodes for actuating a droplet and further includes a nanopore layer for detecting translocation of a tag/second binding member through nanopore is disclosed. An instrument configured to operate a cartridge that includes an array of electrodes for actuating a droplet, an electrochemical species sensing region, and a nanopore layer for detecting translocation of a tag/second binding member through nanopore is disclosed.
