Abstract

Sensor and biosensor technologies have shown rapid progress in recent years. These technologies use nanomaterials have an important place in immobilization materials for recognition analyte molecules. Although fullerens among these materials have attracted much attention in recent years, their number of studies is less than other carbon-based nanomaterials. Thanks to its completely closed structure and at least 30 double bonds, it can be modified from 30 points, which provides a great advantage. At these points, thanks to the ability to modify amine, thiol, carboxyl or metallic groups, modification residues can be created for all kinds of immobilization. According to the zero-dimensional nanomaterial class, fullerens provide an extremely large surface area. Therefore, it provides more biological or non-biological recognition receptors immobilized on this surface area. Moreover, increasing the surface area with more recognition agent also increases the sensitivity. This is the most important parameter of sensor technologies, which is provided by fullerenes. In this book chapter, the development of Fulleren-modified sensor and biosensor technologies are explained with examples and Fulleren modifications are given by figures as Fulleren derivatives. Contribution was made in the method development stage by giving comparison of Fulleren type sensor and biosensor systems.
