Gold nanoparticles in liquid crystals

Thursday, September 01, 2011

Gold nanoparticles are patterned into various cholesteric textures, onto a huge variety of substrates (glass, soft plastic, water), by controlling the film thickness and the interfaces. This demonstration offers a simple bottom-up technique for on-demand nanopatterning of particles over large areas. Potential applications are in the field of soft nanotechnology and optical materials.
