The present invention relates to methods and arrays for use in high resolution imaging of individual nucleic acid molecules and chromatin fragments, including native chromatin fragments. In one aspect, the present invention relates to a chromatin array that includes a transfer platform having a support and a transfer surface layered on the support. The chromatin array also includes a plurality of elongated individual native chromatin fragments coupled to the transfer surface in an orderly pattern suitable for high resolution imaging of the plurality of native chromatin fragments. The native chromatin fragments of the chromatin array include both DNA and histones.
