Master thesis project: Carbon nanotubes as a material for cell-electrode interfacing

Development of new materials for in vitro and in vivo electrical recordings is a challenging task required for a successful brain-computer integration. One of the problems that should be solved is an increase of signal-to-noise ratio, which is especially difficult due to a relatively low magnitude of a neuronal action potential. Introduction of an artificial channels made of a small segments of carbon nanotubes into a cell membrane showed promising results with a perspective of acquiring non-invasive intracellular signals from cells.

Current project aims to further investigate a carbon nanotubes-cell interactions and develop a carbon nanotube-based functional coating for electrical recording devices. The methods used for that include:

  • chemical preparation of small segments of carbon nanotubes from bulk amounts of material
  • incorporation of nanotube segments in a model membrane
  • evaluation of ion flow through the nanotube segment
  • modification of nanotube segments with fluorescent dyes for tracking cell-nanotube interactions
  • confocal microscopy of cells cultured on a nanotube-modified model membrane

The ideal candidate:

  • strong background in organic synthesis
  • ability to independently develop and evaluate efficiency of a protocol
  • interest in neurobiology and electrical recordings

What We Offer:

  • Multifaceted work in an interdisciplinary and international setting, as well as a cooperative work environment;
  • Fantastic research equipment facilities;
  • Forschungszentrum Jülich located close to the interface between Belgium, the Netherlands and Germany and with strong links to the ABCD Region (Aachen, Bonn, Cologne, Düsseldorf) which is one of the leading high-tech regions in Europe.
