Recent Highlights
High yield formation of lipid bilayer shells around silicon nanowires in aqueous solutions
by L. Römhildt et al.
Here we propose a route to merge these two subsystems and report on the formation of highly concentrated aqueous solutions of silanized silicon nanowires wrapped in a lipid bilayer shell. Such aqueous solutions are a versatile tool for characterization purposes and are relevant for newly emerging bioinspired electronics and nanosensorics.

Bio-functionalization of multi-walled carbon nanotubes
by A. Majumder et al.
We present a hybrid approach to functionalize multi-walled carbon nanotubes in aqueous solution, exploring a non-covalent binding strategy. We focus on formation of hybrid complexes consisting of carbon nanotubes decorated by single stranded DNA, non-covalently attached using surfactants as intermediate layers.

Magnetoresistive emulsion analyzer
by G. Lin et al.
We realize a magnetoresistive emulsion analyzer capable of detection, multiparametric analysis and sorting of ferrofluid-containing nanoliter-droplets. Our method offers important complementarity to conventional optical approaches involving ferrofluids, and paves the way to the development of novel compact tools for diagnostics and nanomedicine including drug design and screening.

Parallel arrays of Schottky barrier nanowire field effect transistors: Nanoscopic effects for macroscopic current output,
by S. Pregl et al.
Parallel arrays of bottom up grown silicon nanowire Schottky-barrier field effect transistors (SB FETs) were fabricated. The nanoshaped metal contacts lower the effective Schottky-barrier and lead to higher current densities compared to bulk devices.

Strukturierte biochemische Funktionalisierung von SiO2 Sensoroberflächen zur optischen Detektion verschiedener Analytkonzentrationen,
presented by L. Roemhildt and C. Pahlke at Deutsches Biosensor Symposium in Wildau (11-14th of March, 2013).
Bottom-up synthesis of ultrathin straight platinum nanowires: electric field effect,
by A. Nerowski et al.
We present a route to fabricate the ultrathin high aspect ratio platinum nanowires, which are electrochemically grown in dilute H2PtCl6 solutions. The electric field distribution in the vicinity of the growing nanowires is found to be responsible for their straightness and morphology.
