These films showed a reversible changes in wettability, one of which was indicated by surface contact angle switching between 40° and 59° upon alternating treatment with ethanol and cyclohexane. NMR experimental results of a model molecule suggest that the solvent-responsive wettability of the SAMs could be related with the changes in the relative populations of two stereoisomers of amide. The solvent

In some embodiments, the present invention is directed to methods by which nanoparticle interactions can be controlled, compositions with which such interactions can be controlled, and devices which utilize the control of such interactions. Generally, such methods involve grafting polymer to electromagnetically-functional cores to form a core/shell nanoparticle, assembling a plurality of such core/shell nanoparticles to form an assembly, and exposing the assembly to at least one environmental stimulus to which the polymer is responsive so as to modulate the interparticle interactions of the electromagnetically-functional cores. The present invention is also directed to the compositions resulting from such methods and to the methods and associated devices for controlling the interparticle interactions in such compositions.
