Biochemical Sensors: Graphene Oxide/Hexylamine Superlattice Field‐Effect Biochemical Sensors (adv. Funct. Mater. 23/2021)

In article number 2010563, Chunlei Wan, Wangyang Fu, and co-workers construct superlattices of alternating graphene oxide and hexylamine molecular layers. Owing to a wider interlayer spacing for biomolecular transportation, such graphene oxide/hexylamine superlattices exhibit an exceptional field-effect sensing ability to pH values and DNA molecules in buffer solutions, highlighting the unique potential of graphene 3D hybrid superlattices for biochemical applications by overcoming multilayer aggregation.
