Nano Energy：Advanced transferring of large-area freestanding graphene film by using fullerenes

Professor Fu Jiye's team from the school of Bioscience and Medical Engineering of Southeast University used microporous silicon nitride membrane to study a transfer method of large-area graphene film. Related achievements were published in Nanotechnology with the title of “Advanced transferring of large-area freestanding graphene film by using fullerenes”

Self supporting graphene film has unique physical and excellent chemical performance, and has a wide application prospect in the manufacture of biosensors.Graphene film transferred by using fullerene showed an advanced flatness and a simplicial elementary composition in comparison to those transferred by using polymers. Even through there is trace residue, this stable allotrope of graphene is considered to be almost no impact on biomolecules sensing. These advantages make fullerene transferring method an attractive candidate for fabricating large-area freestanding graphene films, especially using in the field of biochemistry analysis and biosensors.）
