Graphene/MoS2 Heterostructures for Ultrasensitive Detection of DNA Hybridisation

Graphene/MoS2 Heterostructures for Ultrasensitive Detection of DNA Hybridisation

The photoluminescence signals of a graphene/MoS2 heterostructural stacking film are sensitive to environmental charges, which allows the single‐base sequence‐selective detection of DNA hybridization with sensitivity to the level of aM.
