Electrostatic self-assembled nanoparticles based on spherical polyelectrolyte brushes for magnetic resonance imaging

25-May-2018 | Weiqiao Qian; Qin Zhu; Bing Duan; Weijun Tang; Yuan Yuan; Aiguo Hu, Dalton Transactions, 2018

Magnetic resonance imaging (MRI) is one of the most important medical imaging techniques for clinical diagnosis. Contrast agents (CAs) are commonly necessarily used to enhance the imaging quality of MRI and differentiate diseased tissues from normal ones. Herein, we introduced a macromolecular ...

Taking the next step toward inert Mn2+ complexes of open-chain ligands: the case of the rigid PhDTA ligand

25-May-2018 | Kristof Pota; Zoltán Garda; Ferenc Krisztián Kálmán; José Luis Barriada; David Esteban-G ..., New Journal of Chemistry, 2018

In line with our research to find inert Mn(ii) complexes as contrast agents for magnetic resonance imaging, we have studied the aromatic-ring rigidified EDTA-analogue o-phenylenediamine-N,N,N′,N′-tetraacetic acid (PhDTA). The protonation constants (KHi) of PhDTA and stability constants of ...

Synthesis of Gd-functionalized Fe3O4@polydopamine nanocomposites for T1/T2 dual-modal magnetic resonance imaging-guided photothermal therapy

24-May-2018 | Hongying Guo; Hongmei Sun; Hongda Zhu; Huiling Guo; Honghao Sun, New Journal of Chemistry, 2018

A safe, efficient and inexpensive multifunctional nanoplatform is urgently needed for cancer diagnosis and treatment. Herein, we report the first example of fabrication of gadolinium-functionalized Fe3O4@polydopamine nanocomposites and evaluate their potential application in T1/T2 dual-modal ...

Late-stage deuteration of 13C-enriched substrates for T1 prolongation in hyperpolarized 13C MRI

24-May-2018 | Céline Taglang; David E. Korenchan; Cornelius von Morze; Justin Yu; Chloé Najac; Sinan Wang; Joseph E. Ble ..., Chemical Communication, 2018

A robust and selective late-stage deuteration methodology was applied to 13C-enriched amino and alpha hydroxy acids to increase spin–lattice relaxation constant T1 for hyperpolarized 13C magnetic resonance imaging. For the five substrates with 13C-labeling on the C1-position ([1-13C]alanine, ...

Molecular mechanisms for delicately tuning the morphology and properties of Fe3O4 nanoparticle clusters

24-May-2018 | Xiaojun Wei; Lihong Jing; Chunyan Liu; Yi Hou; Mingxia Jiao; Mingyuan Gao, CrystEngComm, 2018

Herein, a polyol method has been explored for producing magnetic iron oxide nanoparticle clusters that are potentially useful as contrast agents for magnetic resonance imaging (MRI), as drug carriers in tumor therapy, and for bioseparation. The oriented attachment growth of primary particles is ...

Amphiphilic complexes of Ho(III), Dy(III), Tb(III) and Eu(III) for optical and high field magnetic resonance imaging

24-May-2018 | Michael Harris; Céline Henoumont; Wannes Peeters; Shuichi Toyouchi; Luce Vander Elst; Tatjana Parac-Vogt, Dalton Transactions, 2018

Lanthanides holmium(III), dysprosium(III), and terbium(III) were coordinated to an amphiphilic DOTA bis-coumarin derivative and then further assembled with an amphiphilic europium(III) DTPA bis-coumarin derivative into mono-disperse micelles. The self-assembled micelles were characterized and ...

209Bi quadrupole relaxation enhancement in solids as a step towards new contrast mechanisms in magnetic resonance imaging

24-May-2018 | D. Kruk; E. Umut; E. Masiewicz; C. Sampl; R. Fischer; S. Spirk; C. Goesweiner; H. Scharfetter, Physical Chemistry Chemical Physics, 2018

Motivated by the possibility of exploiting species containing high spin quantum number nuclei (referred to as quadrupole nuclei) as novel contrast agents for Magnetic Resonance Imaging, based on Quadrupole Relaxation Enhancement (QRE) effects, 1H spin–lattice relaxation has been investigated for ...
