XPS study of ruthenium tris-bipyridine electrografted from diazonium salt derivative on microcrystalline boron doped diamond.
Boron doped diamond (BDD) functionalization has received an increasing interest during the last few years. Such an infatuation comes from the original properties of BDD, including chemical stability or an electrochemical window, that opens the way for the design of (bio)sensors or smart interfaces. In such a context, diazonium salts appear to be well suited for BDD functionalization as they ena...
متن کاملPhotoluminescent multilayer film based on polyoxometalate and tris(2,2-bipyridine)ruthenium
A photoluminescent multilayer film based on Keggin-type polyoxometalate PMo12O40 3 (PMo12) and transition metal complex tris(2,2-bipyridine) ruthenium [Ru(bpy)3] 2+ (Ru(bpy)) was prepared by using layer-by-layer assembly(LBL). The formation of multilayer film was monitored by ultraviolet absorption spectra. The absorption intensity of characteristic peaks increase with a four-layer cycle, indic...
متن کاملImproved electrochemiluminescent label for DNA probe assays: rapid quantitative assays of HIV-1 polymerase chain reaction products.
We describe the characterization and utility of a new electrochemiluminescent (ECL) label for oligonucleotides, utilizing phosphoramidite chemistry. This phosphoramidite of the tris(2,2-bipyridine)ruthenium(II) complex, bis(2,2-bipyridine)(4-[4-(2-cyanoethoxy-N,N-diisopropyl-amino) phosphinoxybutyl]4'-methyl)2,2-bipyridine ruthenium(II) dihexafluorophosphate or Origen phosphoramidite, enables t...
متن کاملSimulation of x-ray absorption near edge spectra of electronically excited ruthenium tris-2,2'-bipyridine.
The L(3) edge x-ray absorption near edge spectrum (XANES) of the ground electronic state and the metal to ligand charge transfer state of ruthenium tris-2,2(')-bipyridine is calculated. The final valence states and energies in the presence of the photoelectron and core hole, and the corresponding transition intensities are computed using time dependent density functional theory with the Becke t...
متن کاملAn electrochemiluminescence biosensor for 8-oxo-7,8-dihydro-2'-deoxyguanosine quantification and DNA repair enzyme activity analysis using a novel bifunctional probe.
A new electrochemiluminescence (ECL) sensor was developed for 8-oxo-7,8-dihydro-2'-deoxyguanosine (8-oxodGuo) quantification and Escherichia coli formamidopyrimidine-DNA glycosylase (FPG) activity assay. The sensor employed a novel spermine conjugated ruthenium tris-(bipyridine) derivative (spermine-Ru) which binds specifically with 8-oxodGuo through a one-step reaction and also acts as an ECL ...
