    1. Nanomedicine

      Monitoring the Hemolytic Effect of Mesoporous Silica Nanoparticles after Human Blood Protein Corona Formation

      Diego Stéfani T. Martinez, Amauri J. Paula, Leandro C. Fonseca, Luis Augusto V. Luna, Camila P. Silveira, Nelson Durán and Oswaldo L. Alves

      Thumbnail image of graphical abstract

      The potential toxicity of protein-corona-coated nanoparticles is mitigated as a result of the steric and electrosteric barriers generated by adsorbed proteins, which largely prevents new interactions between the bare surface of the nanoparticles and red blood cell (RBC) membranes.

      Thumbnail image of graphical abstract

      Co1–xNixFe2O4 nanoparticles are produced by a modified Bradley synthesis. The ferrite particles exhibit superparamagnetic behavior, and Ni2+ substitution has no significant effect on the magnetic response. The cytotoxicity of the ferrites against murine macrophages, osteosarcoma cells, and red blood cells is dose-dependent. The particles do not induce hemolysis at concentrations of up to 0.1 mg/mL.

    1. Post-Synthetically Modified MOFs

      Anchoring of Diphenylphosphinyl Groups to NH2-MIL-53 by Post-Synthetic Modification

      Sonia Castellanos, Karthick Babu Sai Sankar Gupta, Alexey Pustovarenko, Alla Dikhtiarenko, Maxim Nasalevich, Pedro Atienzar, Hermenegildo García, Jorge Gascon and Freek Kapteijn

      Article first published online: 25 AUG 2015 | DOI: 10.1002/ejic.201500678

      Thumbnail image of graphical abstract

      Diphenylphosphinyl moieties were attached to NH2-MIL-53(Al) by means of post-synthetic modification. The resulting Ph2–NH–P=O– side group stabilizes the large-pore configuration of the metal–organic framework (MOF) and modifies the energetic levels and optical properties of the linker. This strategy can be useful for the preparation of new porous materials for electronics, sensing, or catalysis.

      This manuscript reinvestigates the coordination of 2,2′-bipyridine (bpy) to RuII–chlorido–carbonyl precursors. A thorough review of the literature data is followed by our original results and a detailed discussion that wraps up old and new results in a comprehensive frame and shows that the coordination of diimines to RuII–carbonyl precursors has a more complex mechanism than anticipated.

      The primary products from reactions of laser-ablated Hf and Ti atoms with acetonitrile. Both Hf and Ti form π complexes [M–η2-(NC)–CH3], which convert into the insertion and methylidene products. The weaker π and stronger m absorptions in the Hf spectra are in line with their relatively high and low energies, while the observed three products are the most stable steps in the proposed reaction path. The group 4 metal methylidenes are agostic.

      The thermal decomposition of silver compounds with functionalised oximato and nitronato ligands proceeds by intra- and intermolecular redox reactions and can also involve unexpected rearrangements. The quest for suitable molecular precursors by variation of side groups within the ligands is a delicate matter, but can be facilitated by advanced thermal analysis. The correct combination of moieties can achieve decomposition at low temperatures.

      Article first published online: 7 AUG 2015 | DOI: 10.1002/ejic.201500574

      Trinuclear bisphosphine-bridged iron carbonyl clusters are introduced as homogeneous catalysts for proton reduction. Hydrido species form in the presence of acids, and hydrogen is produced electrocatalytically at low overpotential. These electron-rich iron–sulfur clusters are discussed as a promising starting point for the development of photochemical model compounds of iron-based hydrogenases.

      Synthesis of Silica@Ni-Co Mixed Metal Oxide Core–Shell Nanorattles and Their Potential Use as Effective Adsorbents for Waste Water Treatment

      Article first published online: 7 AUG 2015 | DOI: 10.1002/ejic.201500444

      Thumbnail image of graphical abstract

      SiO2@Ni-Co mixed metal oxide core–shell nanorattles are synthesized by the calcination of SiO2@Ni-Co layered double hydroxides at 500 °C. The nanorattles are explored as effective adsorbents for the removal of mixtures of rhodamine B and methylene blue from an aqueous solution. The nanorattles exhibit better adsorption capacity than the individual metal oxides.

      Photoluminescence Modulation in Lan­thanide(III)/Pyrazine-2,5-dicarboxylato/Nitrato Frameworks

      Javier Cepeda, Sonia Pérez-Yáñez, Garikoitz Beobide, Oscar Castillo, Jose Ángel García and Antonio Luque

      Article first published online: 3 AUG 2015 | DOI: 10.1002/ejic.201500484

      Four types of 3D LnIII/pyrazine-2,5-dicarboxylato/nitrato frameworks are synthesized through a solvent-free approach. Their structural diversity is rationalized according to the lanthanide contraction effect and the role played by the nitrate ion (ligand or counterion). The photoluminescence of the complexes can be tuned in response to thermal dehydration.

      Nanoparticles of κ-carrageenan–silica hybrids with narrow size distribution were prepared by using a sol–gel non-emulsion method. Unlike silica particles, these hybrids display thermal sensitivity, which is of great relevance for biomedical applications such as drug encapsulation and thermally controlled drug-delivery systems.

      Borosulfates Cs2B2S3O13, Rb4B2S4O17, and A3HB4S2O14 (A = Rb, Cs) – Crystalline Approximants for Vitreous B2O3?

      Michael Daub and Harald Hillebrecht

      Article first published online: 30 JUL 2015 | DOI: 10.1002/ejic.201500603

      Thumbnail image of graphical abstract

      Cs2B2S3O13 and Rb4B2S4O17 are the first examples of borosulfates with directly connected BO4 tetrahedra. Similar motifs are known for borates and borosulfates. In A3HB4S2O14 (A = Rb, Cs) there are planar layers of B2O3 with trigonal BO3 units and boroxol rings B3O3. These are the characteristic features of vitreous B2O3.

      Orthogonal Functionalization of Ferritin via Supramolecular Re-Assembly

      Silvia J. Spa, Anton Bunschoten, Marcus T. M. Rood, Ruud J. B. Peters, Abraham J. Koster and Fijs W. B. van Leeuwen

      Article first published online: 24 JUL 2015 | DOI: 10.1002/ejic.201500386

      Thumbnail image of graphical abstract

      To investigate the control on ferritin functionalization by supramolecular re-assembly, ferritin with modular functionality and still capable of iron mineralization was created. The ratio in which Cy3-, Cy5-, and non-functionalized subunits were mixed, was indicative for the ratio in which the variable subunits were observed in the re-assembled capsids.

      Article first published online: 23 JUL 2015 | DOI: 10.1002/ejic.201500441

      Novel nanobioconjugates based on Cd-based quantum dots and a PEGylated chitosan derivative as capping ligand have been designed and synthesised by a single-step aqueous route at room temperature. These nanohybrids are luminescent and cytocompatible towards two cell lines tested in vitro, therefore showing potential as biomarkers in nanomedicine applications.

      Recently, Ghosh et al. reported on the fluorescent response of N-(2-aminoethyl)naphthalen-1-amine toward FeII, FeIII, and HgII (K. Ghosh, S. Rathi, P. Gupta, P. Vashisth, V. Pruthi, Eur. J. Inorg. Chem. 2015, 311), concluding that metal binding to the diamine chelator leads to chelation-induced quenching; however, the experimental protocols are incompatible with the aqueous chemistry of FeIII.

      Uniform lanthanide-doped LaVO4 nanospheres functionalized with poly(acrylic acid) are synthesized with a controllable size by a one-pot procedure. As these nanoparticles present strong red (Eu) or near-infrared (Nd) luminescence, are nontoxic for cells, and show high colloidal stability in physiological buffer, they are good candidates as optical biomarkers for in vitro applications.

      The poly(ethyleneimine)-coated magnetic nanoparticles (PEI-MNPs) prepared in this work by oxidative hydrolysis show good reproducibility of size and size distribution. In addition, these PEI-MNPs show only a moderate decrease in the specific power absorption when they aggregate over time. These results render these particles suitable for applications in magnetic hyperthermia.
