Glowing sandwich! Self-organized TiO2-nanotube layers can be used for immunoassay-type sensing. TiO2 nanoparticles coated with CdTe quantum dots are used as signal amplification elements. We show that this, in combination with the advantages of a TiO2-nanotube electrode, leads to an outstanding detection limit in electrochemiluminescent techniques.
