Abstract

An image analysis workstation for analyzing optical thin film arrays is disclosed. One disclosed embodiment relates to individual arrays that comprise a single optical thin film test surface that provides a plurality of discretely addressable locations, each comprising an immobilized capture reagent for an analyte of interest. These are referred to herein as “arrayed optical thin film test surfaces.” Preferably, an individual arrayed optical thin film test surface comprises at least 4, more preferably at least 16, even more preferably at least 32, still more preferably at least 64, and most preferably 128 or more discretely addressable locations. One or more of the discretely addressable locations may provide control signals (e.g., for normalizing signals and/or that act as positive and/or negative controls) or fiducial signals (i.e., information that is used to determine the relative alignment of the arrayed optical thin film test surface within the device.
