Single-Molecule Chiral Recognition on a Surface by Chiral Molecular Tips
Analytical Chemistry, 2008Chiral surfaces attract increasing interest due to their vital role in a variety of scientific fields, such as chiral separation and heterogeneous enantioselective catalysis. The most urgent issue in research on such two-dimensional chirality is a lack of methodologies that recognize molecular chirality on a surface.

Chirality and Surface Twist of DNA Wrapped on Protein Surfaces
Journal of Biomolecular Structure and Dynamics, 1995The surface twist, STw, is a measure of the component of duplex twist associated with the trajectory of the DNA axis wrapped on a protein surface. We calculate STw for various surfaces of revolution, including the cylinder and truncated paraboloid, ellipsoid, and hyperboloid of revolution.

Surface Chirality of CuO Thin Films
Journal of the American Chemical Society, 2006We present X-ray photoelectron spectroscopy (XPS) and X-ray photoelectron diffraction (XPD) investigations of CuO thin films electrochemically deposited on an Au(001) single-crystal surface from a solution containing chiral tartaric acid (TA). The presence of enantiopure TA in the deposition process results in a homochiral CuO surface, as revealed by ...

Mechanically Generated Surface Chirality at the Nanoscale
Physical Review Letters, 2010A substrate coated with an achiral polyimide alignment layer was scribed bidirectionally with the stylus of an atomic force microscope to create an easy axis for liquid crystal orientation. The resulting noncentrosymmetric topography resulted in a chiral surface that manifests itself at the molecular level.

Immobilization of enzyme on chiral polyelectrolyte surface
Analytica Chimica Acta, 2017Chiral D- and L-N-acryloyl aspartic acid (NAsp) polyelectrolyte (PE) surfaces with similar chemical compositions and physical properties but opposite chirality are designed for enzyme immobilization. Enzymes immobilized onto the chiral PE surfaces present high chiral preference, namely L-NAsp PE surface can keep most of the catalytic activity of the ...

Adsorption of Chiral Hydrocarbons on Chiral Platinum Surfaces
Langmuir, 1998Binding energies and configurations of chiral hydrocarbons adsorbed on stepped Pt surfaces are calculated using Monte Carlo simulations. McFadden et al. have recently shown that many stepped single-crystal surfaces have chiral characteristics and that chiral molecules adsorbed on these surfaces should display enantiospecific properties [McFadden, C. F.;

Spontaneous segregation on a hybrid chiral surface
Journal of Computational Chemistry, 2008AbstractSegregation of enantiomers in two‐dimensional adsorbed layers is a process that is usually controlled by anisotropic directional interactions between adsorbed molecules. In this contribution, we propose a simple theoretical model in which the chiral segregation occurs even though the lateral interactions are neglected.

Extended Surface Chirality for Enantiospecific Adsorption
Chemistry – A European Journal, 2008AbstractA rapid development of nanotechnology opens up a way for the fabrication of solid surfaces containing unique adsorption properties. In this article, we present the concept of a chiral nanostructured surface as a potential environment for the separation of chiral molecules. In particular, we focus on the effect of size and shape of the adsorbing
