title: Metal ion-modulated graphene-DNAzyme interactions: design of a nanoprobe for fluorescent detection of lead(II) ions with high sensitivity, selectivity and tunable dynamic range.
abstract: We investigate interactions between graphene oxide and a Pb(2+)-dependent DNAzyme, based on which a Pb(2+) sensor with high sensitivity, selectivity and tunable dynamic range is developed.
