摘要：

The visible and near-infrared (vis-NIR) fluorescence of graphene oxide nanosheets (GO) shows a reversible and sensitive response to ionic strength and pH, in particular a linear physiological pH dependence for monitoring extracellular pH evolution during growth and metabolism of normal and cancer cells.
