RF-titanium dioxide plasma modified graphene coated electrodes for protein sensing

The need for sensitive, selective, rapid and low-cost detection systems for proteins are in crucial demand for diagnostics and real-world applications. Graphene has been an very important nanomaterial for biosensing applications. This study details the preparation of radio frequency (RF)-titanium dioxide (TiO
₂
) plasma modified graphene coated disposable electrodes and their applications for highly sensitive protein detection.
