Dendritic oligopeptides have been reported as useful building blocks for many interactions. Starting from hydrazine, we described an approach to create new dendritic pseudopeptides linked with biological systems, such as cell membrane, as chelate metal, Ni(2+)-nitrilotriacetic acid moieties which could target histidine rich peptides or proteins. Depending on the nature of these new chemical rec...
In this paper, I offer a contribution to the debate on testimony that rests on three elements: the definition of semantic information (Floridi, 2004), the analysis of trust as a second-order property of first-order relations provided in (Taddeo, 2010), and Floridi’s Network Theory of Account (NTA) (Floridi, Forthcoming). I argue that testimony transmits semantic information and it is neither gr...
Don't let go! The Co(3+)-mediated interaction between nitrilotriacetic acid (NTA) and the His6-tag is so stable and inert towards ligand exchange that it has a half-life of 7 days in the presence of imidazole and survives even under strongly chelating as well as reducing conditions, unlike the commonly used Ni(2+) or Co(2+) complexes. Possible applications include the separation of labeled prot...
Investigation of many cellular processes using fluorescent quantum dots (QDs) is hindered by the nontrivial requirements for QD surface functionalization and targeting. To address these challenges, we designed, characterized and applied QD-trisNTA, which integrates tris-nitrilotriacetic acid, a small and high-affinity recognition unit for the ubiquitous polyhistidine protein tag. Using QD-trisN...
Abstract This review concerns the speciation of protactinium in aqueous solution under its both oxidation states +IV and +V. Emphasis is placed on experimental data obtained at trace level but also macroscopic amount leading to determination thermodynamic structural data. Thus, complexation Pa(V) with mineral acids organic acids, mainly polyaminocarboxylic (iminodiacetic acid [IDA], nitrilotria...
The structural integrity of unilamellar vesicles has been studied in vitro and in vivo by use of gamma-ray perturbed angular correlation techniques. These studies utilize 111In3+ weakly bound to the chelator nitrilotriacetic acid as a probe to monitor the percentage of intact vesicles. When complexes of 111In3+ and nitrilotriacetic acid is encapsulated in vesicles, 111In3+ exhibits a fast tumbl...
