Fly Eyes Inspire Anti-Reflective Coating
Scientists at University of Geneva, University of Lausanne (UNIL) and ETH Zurich have artificially developed anti-reflective coating by mixing retinin and wax on different kinds of surface. This was inspired by the observation of eyes of insects which are covered by a thin and transparent coating made up of tiny proturberance with anti-reflective, anti-adhesive properties. Vladimir Katanaev, Professor of Cell Physiology at UNIGE and his team were the first to discover the nano-coating on the eyes of fruit flies (Drosophila melanogaster). The nano-coating resulted from a morphogenesis mechanism that the British mathematician Alan Turing had modelled in the 1950s. This model holds that two molecules are organised automatically to produce patterns in regular patches or strips.
