The aim of this work is to develop a surface‐enhanced Raman spectroscopy (SERS)‐active platform based on a mixture of graphene/Ag nanocomposite and a silver colloid for biomedical applications and to test it in the case of DNA molecules at low pH. Graphene/silver nanocomposites were synthesized by the reduction process and were characterized by transmission electron microscopy, X‐ray powder diffraction...
