Template-Free Synthesis of Ellipsoidal Silica Nanoparticles

  • Henan Zhang (a1) and Daniel L. Akins (a1)

Abstract

For a sol-gel process occurring in a water/oil (w/o) system, the self-assembly of silica nuclei can be controlled by close control of synthesis conditions. We have synthesized ellipsoidal or spherical silica particles by a template-free scheme that involves controlling surface tension on silica nuclei through via use of different volume ratios of a w/o micellar system.
