Fabrication and operation of microarrays A large number of technologies underlie the microarray platform, including the material substrates, spotting of biomolecular arrays, and the microfluidic packaging of the arrays. Microarrays can be categorized by how they physically isolate each element of the array, by spotting (making small physical wells), on-chip synthesis (synthesizing the target DNA probes adhered directly on the array), or bead-based (adhering samples to barcoded beads randomly distributed across the array).
