Anal Chem. 2006 Sep 15;78(18):6674-7.A simple thermal process for the preparation of small Pt nanoparticles is presented, carried out by heating a H2PtCl6/3-thiophenemalonic acid aqueous solution. The following treatment of such colloidal Pt solution with Ru(bpy)(3)2+ causes the assembly of Pt nanoparticles into aggregates. Most importantly, directly placing such aggregates on bare solid electrode surfaces can produce very stable films exhibiting excellent electrochemiluminescence behaviors.
