Abstract

The fabrication and attractive sensing and biosensing performance of platelet graphite nanofibers/polysulfone (PGNF/PSf) composite nanomaterials is described. The PGNF/PSf nanocomposites were fabricated by facile phase-inversion method. Their electrochemical performance was compared to the one of carbon nanotubes/PSf and graphite microparticles/PSf composite. It was clearly demonstrated that PGNF/PSf provides superior voltammetric and amperometric performance for sensing and biosensing over those two other sp² carbon materials. This can be attributed to the unparallel amount of electroactive edge sites on PGNF in which electroactivity is not impaired by the polysulfone binder. PGNF/PSf/glucose oxidase nanobiocomposite was prepared and used for proof-of-concept biosensing of glucose.
