Advances in gold nanoparticle-liquid crystal composites

We present the advancement in the research of the dispersion of gold nanoparticles (GNPs) in thermotropic calamitic liquid crystals. The formation/behavior of surface plasmon resonance (SPR) in GNPs is briefly described. The uniform dispersion of GNPs into liquid crystals along with two important aspects, i.e. tuning of GNP properties by liquid crystal and vice versa, are widely discussed. Overall, the article highlights the advances in the research into GNP-liquid crystal composites in terms of their scientific and technological aspects.
