There is an increasing demand for the use of light-producing
chemical reactions for quantitative detection in biotechnology,
especially with regard to chemiluminescence-based ligand-binding
assays.1 The attractiveness of chemiluminescence as an analytical
tool lies primarily in the simplicity of detection2 since most samples
have no unwanted background luminescence and no optical filters
are required to separate the excitation wavelengths and scatter.2
However, chemiluminescence-based detection is limited by the
quantum efficiency of the chemiluminescence reaction or probe
and the time before depletion of the reactants.2 In this regard, an
increased luminescence yield would clearly benefit overall detectability
and therefore, for bioassays, the sensitivity toward a
particular analyte.
Recently, the interactions of silver nanoparticles with chemiluminescent
species, which resulted in an increase in th
