Composites of carbon nanotubes and poly(3,4-ethylenedioxythiophene, PEDOT) and layers of PEDOT are deposited onto microelectrodes by electropolymerization of ethylenedioxythiophene in the presence of a suspension of carbon nanotubes and polystyrene sulfonate. Analysis by FIB and SEM demonstrates that CNT-PEDOT composites exhibit a porous morphology whereas(More)
A survey is given on the status of developments, concerning a subretinal electronic microphotodiode array that aims at replacing degenerated photoreceptors. Various prototypes have been developed, tested, and implanted in various experimental animals up to 18 months. The fact that electrical responses were recorded from the visual cortex of pigs after(More)
Electrode materials obtained through electropolymerization of 3,4-ethylenedioxythiophene (EDOT) have sparked interest toward applications in neuroscience and neuroprosthetics due to their favorable electrochemical properties and their biocompatibility. However, insufficient mechanical stability had been an unresolved issue and hindered practical(More)
State of the art animal and cell culture models fail to predict the ability of drugs to cross the blood-brain barrier as they lack comparability to the complex human situation. The development of novel pharmaceutics therefore requires in vitro models with human like cell response. Therefore, we are developing a model which mimics the organ environment(More)
Artificial chemical stimulation could provide improvements over electrical neurostimulation. Physiological neurotransmission between neurons relies on the nanoscale release and propagation of specific chemical signals to spatially-localized receptors. Current knowledge of nanoscale fluid dynamics and nanofluidic technology allows us to envision artificial(More)
Chemical stimulation of cells is inherently cell type selective in contrast to electro-stimulation. The availability of a system for localized application of minute amounts of chemical stimulants could be useful for dose related response studies to test new compounds. It could also bring forward the development of a novel type of neuroprostheses. In an(More)
