(2011) Label Free DNA Detection Using Large Area Graphene Based Field Effect Transistor Biosensors. Journal of Nanoscience and Nanotechnology, 11 (6). pp. 5258-5263.Full text not available from this repository.
We describe the fabrication of highly sensitive graphene based field effect transistor (FET) biosensors with a cost-effective approach and their application in label-free Deoxyribonucleic acid (DNA) detection. Chemical vapor deposition (CVD) grown graphene layers were used to achieve mass production of FET devices via conventional photolithographic patterning. Non-covalent functionalization of the graphene layer with 1-Pyrenebutanoic acid succinimidyl ester ensures high conductivity and sensitivity of the FET device. The present device could reach a detection limit as low as 3 X 10(-9) M.
