Biomolecular Assembly of Thermoresponsive Superlattices of the Tobacco Mosaic Virus with Large Tunable Interparticle Distances

摘要

The fabrication of crystalline assemblies, or superlattices, of 1D nanoscale building blocks is of great interest because of the collective properties that may result from the uniform arrangement of the components. For these collective properties to be tuned, control over not only the symmetry of the building blocks but also the distance between them is crucial. Various assembly methods that utilize enthalpic or entropic interactions, such as solvent evaporation, DNA base pairing or charge, have been developed for the fabrication of superlattice structures, as well as strategies based on external magnetic and electric forces.
