A water-soluble nanometer-scale metallocapped polyrotaxane has been prepared by the inclusion complexation of azo-calixarenes with metallo-bridged bis(beta-CD)s, displaying highly selective binding for Ca(2+).

Incorporating the visual discrimination of 2,2'-bipyridine and self-healing properties, a novel photo-switchable metallo-hydrogel system is fabricated using a pincer-type Cu(II) complex and 2,2'-azopyridine.

Different techniques for fabricating long-range plasmonic metallo-dielectric waveguides are discussed. The approaches depend strongly on the material system in use. Specific results are presented for SU8 and PDMS.

A series of mono-functionalized metallo-porphyrin polystyrenes have been synthesized using atom transfer radical polymerization and their self-assembling behavior was studied by electron microscopy showing that the polystyrene tail-length influences the aggregate architecture.

Doping a zinc porphyrin based-sensitizer with antenna molecules, axially held by metallo-supramolecular interactions, enhances the light-harvesting efficiency and the overall photo-conversion efficiency of the solar cells by about 30%.

The novel hydroquinone, (E)-2-(4-hydroxy-3-methyl-2-butenyl)-hydroquinone, and known compound, polyporenic acid C, were isolated as matrix metallo-proteinase inhibitors from the mushroom, Piptoporus betulinus.

conclusions: the prevalence of metallo-beta-lactamase-producing a. baumannii strains detected in this study is of great concern and highlights the need of infection control measures including antibacterial management and prompt identification of beta-lactamase-producing isolates. results: the resistance of a. baumannii isolates against tested antibiotics were as follow: 108 (100%) to cefotaxime...

introduction: pseudomonas aeruginosa is one of the leading causes of nosocomial infections, and antibiotic resistance of this pathogen is an important concern in treating such infections. the current work was conducted to investigate the prevalence of bla-imp, and bla-vim metallo-beta-lactamase (mbl) among clinical and environmental p. aeruginosa isolates obtained from icus of different hospita...
