Structurally patterned pyrolysed three-dimensional carbon scaffolds (p3Dcarbon) are fabricated and applied for differentiation of human neural stem cells (hNSCs) developed for cell replacement therapy and sensing of released dopamine. In the absence of differentiation factors (DF) the pyrolysed carbon material induces spontaneous hNSC differentiation into mature dopamine-producing neurons and the 3D-topography promotes neurite elongation. In the presence and absence of DF, ≈73-82% of the hNSCs obtain dopaminergic properties on pyrolysed carbon, a to-date unseen effi ciency in both two-dimensional (2D) and 3D environment. Due to conductive properties and 3D environment, the p3D-carbon serves as a neurotransmitter trap, enabling electrochemical detection of a signifi cantly larger dopamine fraction released by the hNSC derived neurons than on conventional 2D electrodes. This is the fi rst study of its kind, presenting new conductive 3D scaffolds that provide highly effi cient hNSC differentiation to dopaminergic phenotype combined with real-time in situ confi rmation of the fate of the hNSC-derived neurons. © 2014 WILEY-VCH Verlag GmbH & Co.

We present temperature dependent nanoscale four-contact conductance measurements performed on a submonolayer coverage of cobalt phthalocyanine on Si (111) - (3×3) Ag. The presence of the organic adsorbates suppresses the reversible Ag/Si surface phase transition temperature and reduces the magnitude of the accompanying switching of the surface conductance. The absence of an observable Kondo effect is also discussed in terms of the reported electron transfer between the Ag/Si surface and the Co2+ ion. © 2011 American Institute of Physics. Source

In this work we present high-aspect ratio carbon pillars (1.4 μm in diameter and ∼11 μm in height) on top of interdigitated electrode arrays to be used for electrochemical applications. For this purpose, different types of 2D and 3D pyrolysed carbon structures were fabricated and characterised including surface- and microstructure, electrical and electrochemical properties. A pre-treatment of oxidised Si wafers is introduced to eliminate electrode delamination and ensure structure stability in water during long time-experiments. Additionally, a heat treatment method is reported for regeneration of pyrolysed carbon films with increased film resistance due to oxidation during storage. © 2015 Elsevier Ltd. Source
