Claim:
1. A chip for assays comprising: a solid planar substrate; a two-dimensional array of experiment sites on the substrate, characterized as having a uniform distance between adjacent experiment sites in each row and between adjacent experiment sites in each column; a linear array of alignment sites on the substrate, characterized as having a uniform distance between adjacent alignment sites; and a site free band separating the two-dimensional array and the linear array, the site free band having a width that is greater than the uniform distance between adjacent experiment sites in the two dimensional array; wherein experiment sites in the two dimensional array and alignment sites in the linear array have a surface that is chemically functionalized to bind and retain nucleic acid macromolecules; wherein outside the experiment sites and the alignment sites, the substrate has a surface that resists binding of nucleic acid macromolecules; and wherein the uniform distance between sites in the linear array is a non-integral multiple of the uniform distance between the rows and between the columns in the two-dimensional array.
