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 p M ) for the target biomarkers. In addition, the highly selective nature of the biosensor is demonstrated by detecting low concentrations of the target biomarkers.
