Researchers at RMIT University and the University of Adelaide have joined forces to create a stretchable nano-scale device to manipulate light. The device manipulates light to such an extent that it can filter specific colours while still being transparent and could be used in the future to make smart contact lenses. Using the technology, high-tech lenses could one day filter harmful optical radiation without interfering with vision, or...
