Effects of silver nanoparticles on photochemical processes focusing on luminol chemiluminescence
… a ruthenium complex decay constant and chemiluminescence of luminol and ferricyanide, were studied. The tryptophan fluorescence was slightly enhanced by smaller nanoparticles and showed slight quenching in the presence of larger nanoparticles. The tris (2,2’-bipyridyl ruthenium (II) …

The Role of Metal Ions and Metallo-Complexes in Luminol Chemiluminescence (Catalysis)
Luminol chemiluminescence (CL) has been employed for the sensitive detection of various analytes such as certain transition metal ions and hydrogen peroxide (H(,2)O(,2)). Metal ions and metallo-complexes significantly enhance the light output of the luminol CL reaction (these species are generally …

Characteristics and applications of the enhanced HRP-catalyzed oxidation of luminol
Chemiluminescence (CL) is the process in which the energy from a chemical reaction is released and thus produces an electronically excited species which, upon decay to the ground state, emits light. One of the most efficient chemiluminescent molecules is luminol. As a result of this, luminol has …

The seasonal cycling and physico-chemical speciation of iron on the Celtic and Hebridean shelf seas
Shelf seas represent an important source of iron (Fe) to the open ocean. Additionally, shelf seas are highly productive environments which contribute to atmospheric carbon dioxide drawdown and support large fisheries. The work presented in this thesis describes the seasonal cycle of Fe in the …
