Directed colloidal synthesis of conductive organic–inorganic hybrid mesoscale structures is reported. The technique is simple but allows hierarchical assembly and 2D patterning of materials. A focused laser spot is used to direct the colloidal assembly of nanoparticles into electrically conductive organic–inorganic hybrid mesoscale filaments with arbitrary permanent patterns on a glass surface.
