Rapid development of nanotechnology induced the development of new diagnostic and therapeutic methods in nanomedicine. The novel nanostructures created by nanotechnology, in various forms and morphologies, can find their purpose in a wide range of medical applications such as drug delivery systems, tissue engineering or construction of biosensors.
In this study we focused on synthesis of gold nanoribbons using selected dicationic surfactants. These nanostructures will be used for construction of bionanosensors. The size as well as physical and chemical properties of these nanostructures give plenty ways of functionalization using biological macromolecules (antibodies, nucleic acids etc.) and the possibility to implement them in small devices. The best candidates are nanostructures like nanorods, nanowires and nanoribbons. Nanoribbons were specifically chosen for this study as they are flat shaped and easy to modify.
The nanostructures obtained (mostly gold nanoribbons or nanorods) were characterized by UV–Vis spectroscopy, Atomic Force Microscopy (AFM) and Transmission Electron Microscopy (TEM).
