Abstract
Mesoscale self-assembly relies upon long-range interactions such as van der Waals (vdW-Ld) forces, which must be understood before they may be utilized. We present a study of the vdW-Ld interactions from interband optical properties and Lifshitz theory, across materials including DNA, collagen, ceramics, and carbon nanotubes. A non-local, disproportionate connection between individual interband spectral features and vdW-Ld interaction strength was observed in calculations on synthetic optical spectra. Structurally similar materials including SiO

exhibited similar interband optical properties and Hamaker coefficients, elucidating the role of chemical structure on these effects. Variation of interband features were observed in DNA oligonucleotides from experimental and ab initio results, corresponding to changes in composition and stacking sequence. A cross-material study using the Gecko Hamaker open-source software tool revealed local maxima in the Hamaker coefficient’s anisotropy dependence and a retardation-induced non-monotonicity in certain material configurations. These observations suggest new approaches for mesoscale system design.
