Abstract

Directed assembly of metal oxide nanoparticles with the aid of DNA was investigated. One-dimensional arrangement of zirconia (ZrO ₂) nanoparticles using DNA as a template was shown by TEM observation. It is considered that the DNA-directed assembly of ZrO ₂ nanoparticles is due to the Coulomb interactions between the negatively charged DNA and positively charged ZrO ₂ nanoparticles.
