Gold nanoparticles exhibit many useful optical, electronic, and chemical properties that are important for potential applications in catalysis, sensing, and biomedicine. In this study we demonstrate the synthesis of gold nanoparticles using various derivatives of biomolecule cyclodextrin, which acts as a reducing agent as well as a ligand. Also, due to their nontoxicity, these biomolecules are excellent ligands for biomedical applications as shown in previous studies, where cyclodextrins were used as a drug carrying agent. In our experiments, gold nanoparticles were synthesized with distinct cyclodextrins composed of 6, 7, and 8 glucose subunits (α, β, and γ, respectively). To determine the necessary circumstances for enhancing monodispersity of the gold nanoparticles, the synthesis was performed under various reaction conditions. The photophysical properties and size distribution of the prepared nanoparticles were characterized using ultraviolet-visible spectroscopy (UV-Vis) and dynamic light scattering (DLS). Stability measurements were also conducted as part of the study.
