Graphene/MoS(2) heterostructures for ultrasensitive detection of DNA hybridisation

Adv Mater. 2014 Jul 23;26(28):4838-44. doi: 10.1002/adma.201401084. Epub 2014 May 19.

Abstract

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.

Keywords: DNA; graphene; heterostructures; molybdenum disulfide; ultrasensitive detection.
