IBI-3 - Bioelektronik
Area of research:
One of the major challenges in modern neuroscience is to investigate information processing of neuronal networks with high spatio-temporal resolution and high signal-to-noise ratio (SNR). While microelectrode arrays (MEAs) offer a range of advantages such as their non-invasive nature, the ability to interact with cellular networks over extended times and at multiple sites and excellent temporal resolution, they also exhibit the drawback of recording strongly attenuated signals. A possible approach for the improvement of the recording capabilities of MEA-based devices is to increase the cell-electrode contact via the introduction of additional dimensionality, either through protruding structures that enable phagocytosis-like events (2D+ structures) or via cavities allowing for cellular protrusion into the sensor (Nanocavities).
The project will develop new neuroelectronic interfaces that exploit unique properties of 2D+ nanostructures with a high aspect ratio which are particularly suitable as interface between neurons and electronic devices, since the excellent mechanical coupling to the neuronal cell membrane and in some cases even direct access to the neural- intracellular space allows very high signal-to-noise ratios. The primary focus will be to design, fabricate, measure and optimize nanostraw material, which can be utilized either independently or combined by fabricating hybrid devices with multiple functional layers for electrical recordings. Your tasks within framework in detail:
- Design, fabrication, application and optimization of nanostraw material for extracellular recordings.
- Integration of nanostraw material in MEA technologies
- Characterization of the cell-electrode interface
- Master’s degree (or equivalent) in physics, electrical engineering, material science or a related field
- Proficiency in English
- Advantageous, yet not mandatory, are experiences in biology and/or neuroscience
