Abstract: The present disclosure relates to devices, apparatus and methods of improving the accuracy of image-based assay, that uses imaging system having uncertainties or deviations (imperfection) compared with an ideal imaging system. One aspect of the present invention is to add the monitoring marks on the sample holder, with at least one of their geometric and/optical properties of the monitoring marks under predetermined and known, and taking images of the sample with the monitoring marks, and train a machine learning model using the images with the monitoring mark.

Abstract: Provided herein is a method and device for performing a homogeneous nucleic acid detection assay. The device can contain a pair of plates where one of the plates comprises (i) surface amplification surface; and (ii) target-specific nucleic acid probes that are immobilized on said amplification surface and that specifically binds to a part of the target nucleic acid; and the second plate comprises a sample contact area comprising a reagent storage site that comprises target-specific nucleic acid detection agents that specifically binds to another part of the target nucleic acid. In some embodiments, the device can be read without a washing unbound label from the surface of the device.
