Patent ID: 8133719

Claim:
A method for making an array of randomly disposed concatemers, wherein said method comprises: (a) providing a solid substrate comprising a surface and a plurality of discrete spaced apart regions defined on said surface, wherein the discrete spaced apart regions are arranged on the surface in a regular array, wherein the discrete spaced apart regions bind DNA concatemers through attractive noncovalent interactions, wherein said discrete spaced apart regions are separated by inter-regional areas; and said inter-regional areas are hydrophobic; (b) providing a composition comprising a plurality of DNA concatemers, wherein each concatemer comprises a plurality of monomeric units; (c) depositing said composition on said surface, thereby randomly disposing concatemers on said plurality of discrete spaced apart regions such that at least a majority of said plurality of discrete spaced apart regions comprise a single concatemer bound thereto and said concatemers do not bind to said inter-regional areas.
