Graphene oxide as an efficient signal-to-background enhancer for DNA detection with a long range resonance energy transfer strategy.

A long range resonance energy transfer (LrRET) strategy for label-free and sensitive DNA detection is outlined by introducing graphene oxide (GO) as an efficient signal-to-background enhancer, giving a limit of determination (3σ) of 0.31 nM. This journal is © The Royal Society of Chemistry 2011
