Gold nanoparticles (nanostars and nanospheres) are wrapped with graphene oxide sheets with or without the addition of a Raman dye, as ultrasensitive SERS nanoprobes. The surface of gold nanoparticles is modified with cysteamine to induce positively charged amino groups and help self-assembly of graphene oxide flakes. The resulting nanoprobes show a high Raman signal and an excellent stability under physiological conditions.
