Abstract |
During the last decades, the field of bioelectronics is becoming increasingly
important due to the demand for clinical detection of various diseases. Epilepsy is a
common neurological disorder, affecting millions of people around the world. It is
known that metabolic disturbances are often associated with the seizures of epilepsy.
According to preliminary studies, amongst other biomarkers, glucose levels can be
used for the prediction of incoming seizures, therefore, the creation of specific
bioelectronic devices, such as biomolecular sensors, is of great importance. For
neurological disorder detection, there is a tremendous need for hydrophilic,
biocompatible and highly conductive electrodes in biosensors. Two-dimensional (2D)
graphene-based nanomaterials (NMs) exhibit promising physical, optical and
electrochemical properties for ultrasensitive bioelectronic devices.
In this work, two dimensional (2D) reduced graphene oxide (rGO) based
microelectrodes are developed for use in a biomolecular sensor. The graphene oxide
(GO) films were mainly fabricated by spray gun technique. The topography and the
composition of the GO films were studied by various microscopic and spectroscopic
techniques, respectively. For the enhancement of the electronic properties, an ultrafast
pulsed laser was used for the reduction of the GO material.
