Abstract
The improvisation of graphene oxide (GO)nanosheets by metal nanoparticles without any alterations on the sp2 network helps to enhance the surface enhanced Raman spectroscopy (SERS)effect. Herein, we describe a novel synthesis pathway to produce gold-graphene oxide (Au-GO) nanohybrid via pulsed laser ablation in liquid (PLAL). The gold nanoparticles (Au NP) decorated GO layers via PLAL are extremely pure without any surfactants and other chemical contaminants. The Optical and morphological studies were performed to validate the in situ loading of Au NPs on the GO sheets. Remarkably, these nanohybrids can act as an outstanding SERS platforms for sensing applications.
