• this point of view, SCO complexes are of great interest due to the substantial variation of the real part of their refractive index (n) throughout the entire UV, visible and IR frequency ranges. In our research, we proposed a hybrid, SCO–plasmonic device based on gold nanostructures. Employing electron

• -ammonio-1-propanesulfonate (DAP), and Tween-80 (T80) were utilized. Leaf-like, rugged, dendritic, and tadpole-shaped gold nanostructures were formed in the presence of SDS, CTA, DAP and T80, respectively. Here, we have attempted to explore the ability of eight different lyophilized proteins with
