title: Graphene-supported ferric porphyrin as a peroxidase mimic for electrochemical DNA biosensing.
abstract: A novel peroxidase mimic was designed by loading ferric porphyrin and streptavidin onto graphene, which was used to recognize a biotinylated molecular beacon for specific electrochemical detection of DNA down to attomolar levels.
