Nanoparticle assembly is important for the study and manipulation of plasmonic [1-3], electronic [4-6], and magnetic [7, 8] interactions at the nanoscale because control over the relative placement of nanoparticles allows for the fine-tuning of such fundamental 1242interactions [9]. The desire to integrate these precisely designed materials into higher order constructs across various length scales has led to the investigation of transferrable freestanding nanoparticle superlattice materials where nanoparticle superlattices can be easily combined with other materials or devices to create functional entities [10-13]. Herein, we report a novel method for synthesizing macroscopic crystalline DNA nanoparticle superlattice sheets transferrable to flat, curved, or dimpled substrates without sacrificing control over volume fraction, lattice parameter, or film thickness afforded by the DNA-programmable technique. Large area optical uniformity and preservation of nanoparticle superlattice ordering are confirmed by optical spectroscopy and grazing-incidence small-angle X-ray scattering (GISAXS), respectively. As such, these deliberately designed large-area conformal materials are attractive for next generation sensing [14, 15], plasmonic [16-20], and optoelectronic studies and devices [21-24].
