Resum:
The focus of the present thesis was to explore strategies for the preparation and modification of novel nanoarchitectures based on CNOs to expand their current applications in the construction of novel detection systems with improved performances. These nanomaterials were prepared in a controlled manner by nanodiamond annealing and were deposited on electrode surfaces by simple casting methods. They were successfully dispersed in aqueous solution using a supramolecular strategy and implemented in detection systems for small molecules, proteins and DNA with enhanced sensitivity and improved analytical properties. Although some of the biosensor platforms developed in this work were not fully optimized, it is clear that the use of carbon nano-onions in biosensing has many promising advantages over other nanomaterials. Our results also open up new possibilities for many other applications such as photovoltaics or molecular electronics in which the interfacial and electronic properties of carbon nano-onions can play an important role in the fabrication and performance of these devices.
