Overview

Analytical ultracentrifugation successfully refines gold nanorods, indicating modification of surfactant interactions.

Key Points

  • Main finding shows that modifying surfactant layers can enhance gold nanorod monodispersity.
  • Evidence indicates thicker CTAB layers around gold nanorods affect their sedimentation behavior.
  • The approach utilizes a custom-built analytical ultracentrifugation method to capture real-time data.
  • Significance lies in producing high-quality gold nanorods and reassessing interactions in other nanoparticles.
