pH-Responsive Relaxometric Behaviour of Coordination Polymer Nanoparticles Made of a Stable Macrocyclic Gadolinium Chelate.
Lanthanide-containing nanoscale particles have been widely explored for various biomedical purposes, however, they are often prone to metal leaching. Here we have created a new coordination polymer (CP) by applying, for the first time, a stable Gd(III) chelate as building block in order to prevent any fortuitous release of free lanthanide(III) ion. The use of the Gd-DOTA-4AmP complex as a desig...
متن کاملPicture 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 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...
متن کاملThe Structure of Copper (II) -Histidine Chelate
The binding of Cu(II) by histidine in 1: 2 molar ratio has been investigated. The theoretical number of hydrogen ions displaced from each mole of bound llgand at several pH values was calculated considering all the possible interactions between Cu(II) and histidine involving (a) amino and carboxyl, (b) amino and imidazole, (c) imldazole and carboxyl, and (d) amino, imidazole, and carboxyl group...
