Scientists Marry DNA Origami and 2D Materials to Make Nanoelectronics

Skoltech and international collaborators have demonstrated a DNA‑origami method to deposit organic dye molecules onto a monolayer of molybdenum disulfide (MoS₂) with nanometer‑scale precision. The DNA nanostructures, about 100 nm across, carry dyes in predefined positions, enabling Förster resonance energy transfer that reshapes the semiconductor’s photoluminescence landscape. This proof‑of‑concept shows that organic patterns can be reliably integrated with 2D semiconductors without creating defects. The approach opens a pathway toward nanoscale electronic and photonic components such as optical processors and quantum simulators.
