"made from stable, tunable, inorganic cadmium-based semiconductor compounds... nanoclusters processed into thin films demonstrat circular dichroism (chirality)... controlling film's drying geometry controls structure/ chirality... meniscus-guided evaporation twists linear nanocluster assemblies into helical shapes with light-matter response 2 orders magnitude larger... interact with light from UV to IR... holographic 3D displays, room-temperature quantum computing, ultra-low-power devices, or medical diagnostics"
