Grafting submicron titania particles with gold nanoparticles using droplet microfluidics

A microfluidic method to synthesize gold–titania nanocomposites is presented. Porous TiO2 particles are first loaded with a reducing agent and then suspended in water and mixed with chloroauric acid (HAuCl4) in a droplet-by-droplet manner on a microfluidic chip. The procedure allows strongly reducing the amount of reagents and easy control of the reaction.
