FluidFM-based nanoscale printing for wearable self-powering biomedical real time sensing
What about implantable self-powering devices to monitor biophysical signals at nanoscale? As a part of the interdisciplinary frontier between material science and new biomedical applications, being able to monitor biological or physical markers and signals, allows for a better treatment from both the diagnostic and healing point of view. Among them, biocompatible and non-intrusive wearable monitoring devices, which are so flexible to adhere perfectly to biological tissue, and even to cells like neurons, gain increasing interest. However, fabricating the devices and the electrodes at nano/microscale remains a challenge.
FluidFM is a force-controlled nanopipette, a versatile tool also for 2D patterning and 3D printing in liquid environment, opening the opportunity to manufacture the devices at the sub-micron scale.
We are going to create the devices and electrodes depositing conductive polymers with the FluidFM and then to perform the opportune characterization.
During the project, you will be directly supervised and supported by Dr. Hatim Machrafi, a visiting scientist from the Université de Liège (BE), together with Mengjia Xu, a doctoral student at LBB. You will focus on printing the conductive polymer electrodes at the nanoscale with the FluidFM, optimizing the morphological and electrical properties of the electrodes through parameter tuning during fabrication. You will also measure the electrical I(V) curves of the printed nanoscale electrodes to control the relationship between fabrication parameters and real-time functioning.
If you have electrical engineering and technology, physics, materials, medical and health sciences or approximative background, and are interested, please, send me an email (xumen@ethz.ch) to briefly introduce your past experience and your motivation. Thank you!
