Spatially Resolved Monitoring of Drying of Hierarchical Porous Organic Networks [PDF]
Evaporation kinetics of water confined in hierarchal polymeric porous media is studied by low field nuclear magnetic resonance (NMR). Systems synthesized with various degrees of cross-linker density render networks with similar pore sizes but different ...

The surface accessibility of α-bungarotoxin monitored by a novel paramagnetic probe [PDF]
The surface accessibility of {alpha}-bungarotoxin has been investigated by using Gd2L7, a newly designed paramagnetic NMR probe. Signal attenuations induced by Gd2L7 on {alpha}-bungarotoxin C{alpha}H peaks of 1H-13C HSQC spectra have been analyzed and ...

Optimising the relaxivities of Mn2+ complexes by targeting human serum albumin (HSA) [PDF]
[Abstract] We report two novel macrocyclic ligands based on the 1,4-DO2AM platform (1,4-DO2AM = 2,2′-(1,4,7,10-tetraazacyclododecane-1,4-diyl)diacetamide) and containing two benzyl groups attached either to the nitrogen atoms of the macrocyclic unit (1,4-

Unveiling Dipolar Interaction‐Driven Magnetic Field Inhomogeneities in T2 MRI Contrast Agents
In this study, chemically designed nanoscale‐distance‐tuned based on silica‐coated iron oxide nanoparticles are used to investigate how dipolar interactions affect magnetic resonance imaging (MRI) contrast. By varying shell thickness, researchers modulated dipolar interactions and observed an exponential increase in transverse relaxivity (r2) that ...

In the family of Mn2+ complexes formed with pentadentate bispidine chelates, functional groups that do not interfere with metal coordination can play a significant role in enhancing kinetic inertness and proton relaxation efficacy. Mn2+ bispidine complexes combine unprecedented kinetic inertness with high relaxivity and are under scrutiny as potential ...

The fluorinated CDTA‐bisamide derivative ligand, L2, forms a stable and highly inert complex with Mn2+. MnL2 has one inner sphere water coordinated to the central metal ion, hence good proton relaxivity, and the paramagnetic metal ion induces important acceleration of 19F relaxation, provides good signal‐to‐noise ratios on 19F phantom UTE MR images ...

High relaxivity Mn2+-based MRI contrast agents [PDF]
[Abstract] Stable Mn2+ mono- and binuclear complexes containing pentadentate 6,6′-((methylazanediyl)bis(methylene)) dipicolinic acid coordinating units give remarkably high relaxivities due to the presence of two inner-sphere water molecules.
