摘要：

The interactions of bovine serum albumins (BSA) with Au-Ag core-shell nanorods have been studied using fluorescence spectroscopic techniques. It was observed that Ag coated Au nanorods exhibit higher fluorescence quenching efficiency compared with bare Au nanorods. The fluorescence quenching efficiency could be further improved by increasing the aspect ratio or Ag shell thickness of the Au nanorods. Furthermore, the quenching efficiency to BSA is increased as the concentration of BSA is decreased. The physical origin has been illustrated by calculating the dielectric environment dependent fluorescence quenching based on quasi-static theory and fluorescence energy transfer of dipole-dipole coupling.
