ABSTRACT:
The invention provides a metal nanoparticle comprising a metal and a chiral and/or thiolate group bonded to the metal. The monolayer-protected metal nanoparticle may be used as a chiral dopant in a liquid crystal. Accordingly, the invention also provides a colloidal suspension or dispersion comprising a metal nanoparticle comprising a metal and a chiral and/or thiolate group bonded to the metal, and a liquid crystal.
