Higher-Order Structures Assembly of Gold Nanorods Caused by Captopril in High Ionic Strength Solutions
Abstract:The ability to construct self-assembled architectures is essential for the exploration of nanoparticle-structured properties. It is one of good strategies by employing molecule-modificated nanoparticles to prepare new materials with particular properties. Herein, we found that captopril (Cap), a biocompatible medicament, could adjust and control the formation of self-assembled gold nanorods (Au-NRs) in high ionic strength solutions. The assembly is in higher-order structures containing both end-to-end and side-by-side orientations. Furthermore, these structures of Au-NRs could be served as plasmonic waveguide in future biological nanodevices.
