Neurological disorders are an increasing problem to the public health. It is well known that neurotransmitters play important role in many of these diseases. In this thesis, new carbon nanomaterials were fabricated and studied and their applicability to electrochemical detection of neurotransmitters was investigated. The ability to measure neurotransmitters fast and reliably is considered to be one of the key ele-ments when designing new treatment methods for neurological disorders.
This thesis produced the following results: (i) two completely new sensor materials that combine the best properties of the initial components were realized (ii) applica-bility of the newly produced hybrid carbon nanomaterials was proven with clinically relevant neurotransmitter concentrations (iii) detailed chemical and structural prop-erties of many different carbon nanomaterials were reported and (iv) nanoscale tailoring of carbon nanomaterials was proven along with the ability to integrate these carbon nanomaterials to multimaterial structures.
Based on the results the sensors produced by combining different allotropes of carbon show great promise in real time detection of neurotransmitters.
This thesis provides new information about structural and chemical properties of carbon nanomaterials as well as brings these materials significantly closer to actual sensor applications.
