SUMMARY:On the twist: Chirality at surfaces - Stephen Driver\, Surface Sci

DESCRIPTION:In living organisms\, chirality - the property of an object th
 at it cannot be superposed on its mirror image - is fundamental. Key bioch
 emical building blocks\, such as amino acids and sugars\, are chiral\, and
  occur in one enantiomeric form\; getting the chirality right is also cruc
 ial in pharmaceutical manufacture. A vision of utilising metal surfaces as
  heterogeneous catalysts for asymmetric synthesis\, or in enantiomer-discr
 iminating biosensors\, underpins the current drive to understand how they 
 interact with chiral adsorbates. In this talk\, I will discuss different m
 anifestations of chirality at surfaces\, using amino acids adsorbed on Cu 
 surfaces as an archetype. I will focus in particular on the subtle interpl
 ay between molecular\, footprint\, and self-organisational chiralities\, a
 nd how we can tip the playing field by using intrinsically chiral surfaces
 .
