Researchers in the US have used DNA molecules as a scaffold to help them assemble arrays of quantum rods in an ordered, controlled way. By depositing the rods onto this patterned framework, the team at the Massachusetts Institute of Technology (MIT) kept the rods evenly spaced with their nanostructures aligned in a specific direction, which could be useful for applications such as virtual reality devices and micro-light-emitting diodes (microLEDs) in next-generation displays.
