Abstract:
Provided herein are compositions, methods, systems and apparatuses for use in preparing arrays of molecules or other compounds. The systems include beads which are linked to the molecules or other compounds to be arrayed. The arrays are prepared by depositing the bead-molecule complexes onto a surface. The bead-molecule complexes can be used to prepare an array of single molecules, where each single molecule is attached to a surface at a single location on the surface. In one exemplary embodiment, the molecules to be deposited can include nucleic acid.
Abstract:
The disclosure relates generally to compositions, systems, and methods for use in preparing single molecule arrays, for example, arrays of single nucleic acid molecules, as well as arrays formed using such compositions, systems and methods by using a spacer which restricts the spacing between adjacent components of the array. In an exemplary embodiment, the array is formed by contacting a surface with a spacer-anchor complex including one or more spacers linked to an anchor, wherein the spacer comprises a linear or branched polymeric molecule folded to form a three-dimensional shape of desired size dimensions. The size of the folded spacer may optionally be adjusted to modulate the spacing distance between adjacent array components.
