Biosensors, based on graphene-encapsulated nanoparticle arrays, for highly sensitive and selective detection of breast cancer biomarkers are successfully demonstrated. The increased surface-to-volume ratio significantly helped in lowering the detection limits (1 pM) for the target biomarkers. In addition, the highly selective nature of the biosensor is demonstrated by detecting low concentrations of the target biomarkers.
