Thousand-Fold Increase in Optical Storage Density by Polychromatic Address Multiplexing on Self-Assembled DNA Nanostructures

A super-resolution optical storage technique enabled by DNA nanotechnology and the design of resonance energy transfer (RET) networks are demonstrated. The enhancement in storage density stems from non-linear interactions between excitons on the nanostructured RET circuits, which permit large-scale multiplexing with a small set of addressing wavelengths and a single output channel.
