Picture of a chelate in exchange: the crystal structure of NaHoDOTMA, a 'semi'-hydrated chelate.
Crystallography generally only provides static structural information. This can render it an ineffective technique for probing dynamic solution state processes. A crystal of HoDOTMA affords unique structures that effectively represent that of a lanthanide tetra-acetate chelate mid-way through the water exchange process.
متن کاملSynthesis, structure, immobilization and solid-state NMR of new dppp- and tripod-type chelate linkers
Chelating phosphines incorporating ethoxysilane functions for immobilizations have been synthesized and fully characterized. (EtO)Si(CH2PPh2)3, (EtO)2Si(CH2PPh2)2, and Si(CH2PPh2)4 could be prepared in high yields from cheap starting materials. The ethoxysilanes, as well as a Pd complex thereof have been characterized by X-ray structures, and immobilized on silica. The success of the immobiliza...
متن کاملImmunofluorometry of choriogonadotropin by time-resolved fluorescence spectroscopy, with a new europium chelate as label.
We describe a new "sandwich"-type non-isotopic immunoassay for human choriogonadotropin (hCG) in serum. In the assay, hCG is captured by a beta-subunit-specific monoclonal antibody, which is immobilized in a white microtiter well. The sandwich is completed by adding a second biotinylated monoclonal antibody specific for the whole hCG molecule. The degree of binding of biotinylated antibody, whi...
متن کاملGadolinium chelate-associated nephrogenic systemic fibrosis.
Correspondence to: Dr Kei Pin Lin Tel: (65) 6222 3322 Fax: (65) 6326 5242 Email: binglin8@ yahoo.com.sg Nephrogenic systemic fibrosis (NSF) is a rare multisystem disease characterised by widespread tissue fibrosis. It is recognised for its epidemiological association in patients with chronic renal failure, after administration of gadolinium-chelate magnetic resonance (MR) contrast agent, partic...
متن کاملChelate Extraction of Metals into Ionic Liquids
In the solvent extraction of metal cations into ionic liquids, use of Brønsted acid-type chelate extractants has some advantages including simplicity in controlling extraction selectivity by selecting suitable aqueous phase pH values and simple back-extraction recovery of the extracted metals using acid solutions. In this review, various fundamental and applied research on metal extraction usin...
