Single-layer CVD-grown graphene decorated with metal nanoparticles as a promising biosensing platform

► We have developed a methodology to produce single layer graphene sheets decorated with metal nanoparticles as a biosensing platform. ► Electroless deposition of noble metals nanoparticles on graphene (Au, Pd, Pt, Ag, Rh, Ir) is possible with the presented methodology. ► Versatility, reproducibility and large-scale integration are key features of the presented methodology. ► Integration of different biomolecules (antibodies, peptides, DNA sequences, enzymes, etc.) is compatible with the presented biosensing platform.
