DEVICES AND METHODS FOR SAMPLE ANALYSIS

Last updated:

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. Additional 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.
