Chiral surfaces

Our group among the first to utilize chiral self-assembled monolayers (SAMs) for the preparation of chiral Nano surfaces for chiral resolution by crystallization. In a series of papers, my research group has shown that chiral SAM surfaces can be employed as resolving auxiliaries in the crystallization of the amino acids form solutions.

Mesoporous carbon

Chiral inorganic nanostructures

Recently we presented an innovative new type of chiral surfaces based on the combination of chiral monolayers (SAM) coated with ceramic nanolayers that preserve the enantioselectivity nature of the chiral SAM and enable its protection.  These surfaces can lead to new class of chiral nano-surfaces with improved characteristics that are necessary for any chiral application.
