ChemPlusChem 5/2015: Potpourri
Crystallin protein nanofibrils obtained from fish eye lenses served as platforms for immobilizing enzymes. Luigi Sasso and Juliet Gerrard also designed the picture on the back cover of this issue based on this research.
Ramon Martinez-Manez has developed a new chalcone-based probe for the chromo-fluorogenic sensing of trications over mono- and divalent cations. The subtle interplay at the phase interface of CuO deposited on copper-doped CeO2 nanospheres provided Hongxiao Yang with an excellent catalyst for CO oxidation at ambient temperature. In the research featured on the front cover Takeo Ito and Kasuhito Tanabe describe the surface modification of silica nanoparticles with phospholipids inside living cells (cover profile).

Ultrafine Cu2NiSnS4 nanotubes with an average diameter of 4 nm have been synthesized through a simple strategy using a nanoconfined solvothermal solution within anodic aluminum oxide pores. The as-prepared nanotubes have a preferential growth direction of <100> (see figure).

The straight and narrow: The structurally characterized linear trinuclear manganese(II) complex [Mn3(L)(N3)4]⋅2 H2O (see figure) catalyzed the epoxidation of olefins with tert-butylhydroperoxide with a turnover number (TON) greater than 950 and was found to be ferromagnetically coupled with J1=+1.84(1) cm−1.

In a pinch: The non-nearest-neighbour contribution of a single hydrogen bond to RNA folding has been investigated by single-molecule manipulation using optical tweezers (see figure). Disruption of a single hydrogen bond, by the replacement of a single RNA U⋅U pair with a U⋅C pair, results in an increase in the rate of mechanical unfolding and more frequent misfolding.

Ordered nano-superstructures: When polymer templates containing pore networks are subjected to specifically optimized electroless plating reactions, self-supporting arrays of cross-linked metal nanotubes are obtained (see figure). Due to their well-defined structure, high surface area, and porosity, these materials are promising unsupported catalysts; this is demonstrated in the amperometric detection of hydrogen peroxide.
- Poly(benzoxazine)s Modified with Osmium Complexes as a Class of Redox Polymers for Wiring of Enzymes to Electrode Surfaces

Wiring of enzymes: A new class of redox polymers based on benzoxazines modified with Os complexes (see picture) have been synthesized and used as an immobilization matrix for glucose oxidase in the amperometric detection of glucose. The electrochemically induced polymerization of the benzoxazine monomers allows non-manual deposition of the active enzyme layer onto the electrode surface.
