Abstract
According to various embodiments, a method is provided that comprises washing an array of DNA-coated beads on a substrate, with a wash solution to remove stacked beads from the substrate. The wash solution can include inert solid beads in a carrier. The DNA-coated beads can have an average diameter and the solid beads in the wash solution can have an average diameter that is at least twice the diameter of the DNA-coated beads. The washing can form dislodged DNA-coated beads and a monolayer of DNA-coated beads. In some embodiments, first beads for forming an array are contacted with a poly(ethylene glycol) (PEG) solution comprising a PEG having a molecular weight of about 350 Da or less. In some embodiments, slides for forming bead arrays are provided as are systems for imaging the same.
