TL;DR: A range of tris-(4,4′-substituted-2,2′-bipyridine) complexes have been synthesized and characterized electrochemically with respect to their ability to act as electron transfer mediators for redox enzymes, notably glucose oxidase (GOD, EC 1.1.4) of Aspergillus niger as discussed by the authors.

TL;DR: In this paper, the effect of exposure temperature and that of post-exposure thermal annealing on CO vibrational bands suggest that the multicaronyl species transform progressively to monocarbonyl forms which are in turn identified as precursors to the methylene groups in the presence of hydrogen.

TL;DR: In this article, the authors describe the preparation and characterization of mono-and bilayers of three newly synthesized disulfide-bearing lipids and of mixed bilayers containing conventional phospholipids adsorbed onto gold substrates by the self-assembly technique.

TL;DR: In this article, the synthesis and photophysical characterization of several complexes of Ru(II) containing 4,4′-di(carboxyphenyl)-2,2′-bipyridine (DCPB) and related bipyridine ligands are reported.

TL;DR: A ferrocene-derivatised detergent, (11-ferrocenylundecyl) trimethylammonium bromide (FTMAB), when oxidised to the corresponding ferricinium ion, was found by electrochemical studies to be an effective electron acceptor for reduced glucose oxidation of Aspergillus niger and thus acts as a electron-transfer mediator between glucose oxidase and a working electrode held at a potential sufficiently positive to reox

TL;DR: A Ca2+ sensor based on the admittance change of synthetic membranes supported on derivatized silicon electrodes is reported in this paper, where the ion-sensitive membranes consist of mixed monolayers of phospholipid and the Ca2-ligand ETH 1001.
