A graphene conjugated oligomer hybrid probe for light-up sensing of lectin and escherichia coli

A graphene conjugated oligomer hybrid probe for light-up sensing of lectin and escherichia coli

A water-soluble neutral fluorescent conjugated oligomer (FBT) is integrated with graphene oxide (GO) to form a hybrid nanoprobe with extremely low fluorescence background due to the robust quenching capability of GO. The contact between GO and FBT can be effectively shielded by Concanavalin A becaus...
