摘要：

Chemical Equation Presented" The crystallization events occurring in a drying droplet containing DNA-capped nanoparticles were probed by means of small-angle X-ray scattering (SAXS; the picture shows a series of 1D SAXS patterns recorded over time). Unusual nanoparticle supracrystals form that are both soft and elastic with continuously scalable crystalline states over a wide range of lattice constants. © 2010 Wiley-VCH Vertag GmbH & Co. KGaA."
