Real-time monitoring of neuronal cells with graphene biosensor
Graphene is a one-atom-thick, honey-comb arrangement carbon atoms with extraordinary electrical and mechanical properties. Here, we present a novel microfluidic approach for creating a stable ink from this wonder material. This conductive ink is further printed on a flexible substrate and consolidated with electrostatic field and thermal processing. The produced micro electrode array is utilized to monitor the change in electrical properties of rat dopaminergic neuronal network during the degradation stages leading to cell death. This study is aimed to broaden the understanding on the underlying electrochemical events during the neurodegeneration process, caused by traumatic brain injury and disorders such as Parkinson’s disease.
