Conformation and activity of lysozyme on binding to two types of gold nanorods: A comparative study
چکیده انگلیسی
The unique morphology of anisotropic rod-shaped gold nanostructures has offered new prospects for biomedical and biosensing applications. This study investigates the interaction of two types of rod-shaped nanostructures, gold nanorods and gold nanorices with lysozyme as a model protein, comparing the probable structural, activity and kinetic stability alterations. Circular dichroism spectropolarimeter revealed that lysozyme retains high fraction of its native conformation in the presence of both nanostructures, with a slight increase in the helical and beta content. Upon the protein adsorption on both types of nanorods, kinetic studies showed maintenance of enzymatic activity, together with increase in the enzymatic affinity and kinetic stability at high temperature. Comparatively, gold nanorice induced better effect on the activity and stability of enzyme than that of gold nanorod. This study might open new insight into potential applications of gold nanorods as nanocarriers for genes and drugs; provided that the toxicological aspect of cationic surfactant-coated nanostructure is taken into consideration.
