      Front Cover: On-chip control of magnetic particles (Phys. Status Solidi A 5/2012)

      During the last years magnetic micro- and nanoparticles have emerged as powerful tools in the fields of cancer treatment, bioassays, contrast enhancement or labeling on the micron- and submicron-scale. Advances in controlling the dimensions, magnetic properties, and surface chemistry of particles have opened up various new approaches, particularly for lab-on-a-chip applications. These applications emphasize the need for tools to collect and handle magnetic particles in an efficient and reliable way. Optical and magnetic tweezers fulfill these requirements but are only applicable in a limited way to on-chip experiments. Recently, microstructured conducting wires have been used to collect and move magnetic micro- and nanoparticles in lab-on-a-chip approaches. A particularly versatile architecture is given by orthogonal layers of parallel microwires on a chip surface to induce highly localized magnetic fields. Rinklin et al. (pp. 871–874) investigate different current patterns for magnetic actuation and present simple yet efficient protocols for the collection and separation of micro- and nanoparticles without the necessity of external magnets. The cover image illustrates an exemplary collection and actuation experiment. To the left, the particles are collected from a homogeneous suspension. The particle cloud generated in this way can then be moved at the chip's surface as shown in the schematic and the corresponding image series.

      Back Cover: Ultra-thin anodic alumina capacitor films for plastic electronics (Phys. Status Solidi A 5/2012)

      Andrei Ionut Mardare, Martin Kaltenbrunner, Niyazi Serdar Sariciftci, Siegfried Bauer and Achim Walter Hassel

      Article first published online: 25 APR 2012 | DOI: 10.1002/pssa.201290010

      In plastic electronics polymer substrates are combined with stacks of thin metallic, dielectric and semiconducting films to form flexible devices. While the demonstration of active components is highly advanced there is a considerable lack in the development of passive elements. Commonly available capacitors use aluminium or tantalum foils with their oxides as dielectric insulator. The highest performance in oxide formation is achieved by anodisation. A versatile approach for the fabrication of thin film capacitors for plastic electronics by potentiostatic anodisation of aluminium is reported by Mardare et al. (pp. 813–818). The back cover image illustrates such a thin film capacitor with an anodized aluminium oxide dielectric and aluminium electrodes on a PEN substrate and demonstrates the high mechanical flexibility of the fabricated capacitors. Such capacitors may potentially be useful as passive components in flexible plastic electronic circuits.

      Frontispiece: Simulation-based investigations on noise characteristics of redox-cycling sensors (Phys. Status Solidi A 5/2012) (page 880)

      Enno Kätelhön and Bernhard Wolfrum

      Article first published online: 25 APR 2012 | DOI: 10.1002/pssa.201221919

      Thumbnail image of graphical abstract

      In recent years, nanocavity redox cycling has evolved into an interesting technique for a wide range of sensing applications. The sensor design is based on two closely-spaced and individually-biased electrodes that are incorporated into a nanofluidic channel. This setup enables the repeated participation of certain molecules in subsequent redox reactions at the two electrodes, hence leading to a strong amplification of the electrochemical signal. Kätelhön and Wolfrum (pp. 881–884) describe a simulation framework for the modeling of electrochemical processes within such nanocavity redox-cycling devices.

      The image shows an illustration of a random-walk approach for the simulation of the redox-cycling effect. A single molecule trajectory is indicated; differently coloured spheres specify the molecule occupying different oxidation states throughout the molecules pathway.
