中文摘要	a non-destructive, safe and practical strategy to produce high quality graphene in high yield is urgently required, since this would pave the way for a wide range of applications of graphene in the future. here we present a ph-responsive water-dispersible method for the exfoliation and functionalization of graphene by using lysozyme. the ph-responsive dispersion of graphene may be useful for the reversible assembly of multicomponent/multifunctional nanohybrid materials and nanoscale electronic devices. more importantly, composites can be easily constructed through the interactions between disulphide groups in lysozyme and gold nanoparticles (aunps). the resulting graphene-aunps composites show excellent catalytic activity towards reduction of o-nitroaniline by nabh4. since lysozyme is low cost and has antibacterial properties, and has been widely used in food preservation, medicine and the pharmaceutical industry, our approach may open a new scalable route for the manufacture of high-quality, nondestructive graphene for practical applications.
