Abstract
A digitally encoded microflake includes a polymer layer, which has a top surface and a bottom surface substantially parallel to the top surface. At least one of the top surface and the bottom surface is to be coupled to target-specific probes for bonding with a target analyte. The microflake is identified by a binary sequence of bits encoded by an edge outline on a plane substantially parallel to the top surface and the bottom surface. The bits in the binary sequence are encoded at respective predefined locations surrounding the edge outline.
