Embedding nanoparticles in LCDs could lead to advanced displays

Liquid crystal displays (LCD) have become an integral part of our everyday life. LCDs are everywhere, on your digital watches, cameras, iPods, laptop computers, television screens or car navigation displays. LCDs get their name from the special liquid crystal solution that is contained between two thin glass plates inside the display. Recent research findings suggest that embedding doped metal nanoparticles (MNP) in liquid crystal materials increases the performance of certain display devices. So far, however, the main problem with this approach has been that the inclusion of nanoparticles destabilizes the LC material. Researchers have now succeeded in synthesizing metal nanoparticle embedded stable liquid crystals in a single step, without using any external reducing and stabilizing agents. As a bottom-up strategy, this work is a further step towards synthesizing three-dimensional macro structures using small nanoparticles as building blocks, and an elegant method in fabricating soft organic architectures; particularly when it is combined with electronic, magnetic or photonic properties of inorganic materials.
