AB  - Graphene and graphene derivatives, including graphene oxide (GO) and reduced GO 
      (rGO), have attracted remarkable attention in different fields due to their 
      unique electronic, thermal, and mechanical properties, whereas the fluorescence 
      property is rarely been studied. This paper reports on metal-enhanced 
      fluorescence Au@SiO2 composite nanoparticles adsorbed graphene oxide nanosheets, 
      where the silica-shell is used to control the distance between gold-core and 
      fluorophore GO, and a positively charged polyelectrolyte poly(allylamine 
      hydrochloride) (PAH) is used to adsorb the negatively charged silica-shell and GO 
      by layer-by-layer assembly (LbL) approach. The silica-shell around the 80 nm 
      gold-core can be well-controlled by ending the reaction at different times. 
      Various analytical techniques were applied to characterize the morphology and 
      optical characters of the as-prepared particles. A more than three-fold increase 
      of the fluorescence intensity of GO was obtained.
