Nanocomposites: Graphene–Ruthenium(II) Complex Composites for Sensitive ECL Immunosensors (Small 4/2014)
Source abstract
Abstract
Ru-PTCA/G nanocomposites are synthesized via a one step synthesis procedure under moderate conditions followed by covalent attachment of an amine derivative Ru(II) complex through amide bond formation. As X.-H. Xia and co-workers report on page 706, the product shows good electrochemical activity and ca. 21 times higher luminescence quantum efficiency than the adsorbed Ru(II) complex. A solidstate electrochemiluminescent (ECL) immunosensor is developed based on the Ru-PTCA/G nanocomposites for sensitive detection of α-fetoprotein (AFP). The ECL peak intensity in the presence of AFP is much lower than that in the absence of AFP due to the insulating effect of the formed antigen-antibody complex, which inhibits the electron transfer and the mass transfer of tripropylamine to the surface of the Ru-PTCA/G modified electrode.
