Enantioselective crystallization on nanochiral surfaces.

In the past decade, chiral nanostructured crystalline surfaces have received great attention due to their potential applications to fields such as stereoselective chemical synthesis, separation of chiral compounds, new thin film devices for optical and electronic applications, and nanotechnology. This tutorial review presents an overview of nanochiral surfaces with emphasis on our group's recent advances in enantioselective crystallization on nanostructured chiral surfaces. We also focus on techniques for characterization of nanochiral surfaces and introduce a new method: polarized near-field scanning optical microscopy (NSOM) for studying chirality at the nanoscale.
