Abstract
An encoded microparticle having a spatial code is provided; and a set of encoded microparticles possessing subsets each provided with a distinguishable spatial code, wherein the codes comply with a pre-determined coding scheme. Presented are also methods of using the encoded microparticles in various biological assays, such as various multiplex assays and visualizing them by creating a digital image of the encoded microparticles and determining whether false positives are present. Further are provided methods of manufacture of the encoded microparticles which employ ferromagnetic nanoparticles applied using spin-on-glass techniques.
