One-pot green synthesis of graphene oxide/gold nanocomposites as SERS substrates for malachite green detection

In this contribution, graphene oxide/gold nanoparticle (GO/AuNPs) hybrids were in situ fabricated through a green one-pot procedure by using tyrosine as an environment friendly and biocompatible reducing agent, which can be used as highly efficient surface enhanced Raman scattering (SERS) substrates with the enhancement factor at 3.8 × 10(3). The as-prepared GO/AuNPs hybrids have good biocompatibility, providing the prospect of applications for...
