Fabricating gold nanoparticle–oxide nanotube composite materials by a self-assembly method

“…Gold has become a favored coating material because of its simple synthetic procedure and chemical functionality [20]. For example, Au particles have been widely used for electronic and biological applications [13,14]. Self-assembly of nanoparticles becomes more and more important because novel collective properties will be produced in the ordered array of nanoparticles.…”
