The research, led by Monash University’s Yuefeng Yin and FLEET chief investigator Nikhil Medhekar, with Jiri Cervenka at the Czech Institute of Physics (Academy of Sciences of the Czech Republic), was a systematic study of the role of the surface coverage and adsorption geometry on the electronic structure of DNA/RNA nucleobases on graphene.

There is considerable excitement about graphene-based biosensors. In particular, the material’s unique structure and electronic properties offers great potential for rapid, reliable DNA/RNA sensing and sequencing. A recent study has defined key interactions as DNA/RNA nucleobases are adsorbed onto graphene, and identified specific improvements to current graphene-based biosensing, to improve sensitivity.
