Purification of distinct nano shapes from a mixtures of rods and spheres

Abstract

This research investigates the complex processes involved in optimizing assembly conditions to achieve more precise control over the arrangement of gold nanorods (GNRs). The focus is on examining the complex morphology and refinement of GNRs coated with cetyltrimethylammonium bromide (CTAB) within liquid crystalline (LC) structures, with an emphasis on quantifying intertwined domains and the coexistence of diverse particle shapes. The study reveals the presence of morphologically refined arrays of gold nanorod superstructures and explores the influence of factors such as steric hindrance and surface energy on the unique behaviors of these nanostructures in aqueous environments. A combination of experimental and theoretical methods uncovers the significance of energy variances in improving separation efficiency and elucidates the relationship between absorbance, density, and interparticle distances. The research underscores the importance of optimal aspect ratios and their impact on liquid crystal phases, offering valuable insights for the advancement of nanoparticle systems and future innovations in this domain.
