Abstract
A novel electrochemiluminescence (ECL) sensor based on titanate nanotubes (TNTs)/tris(2,2′-bipyridyl)ruthenium(II) ()/Nafion Composite film-modified on glass carbon electrode was developed. Favorable electrochemical activities and excellent ECL emission stability were obtained as TNTs have very strong and stable adsorption toward
. The stability of the sensor was further enhanced by the employment of Nafion during the process of composite synthesis rather than electrode modification. As a consequence, the proposed sensor fabrication approach was simpler, faster, and especially more economical for reagent use, compared with some conventional methods.
