Master Thesis - Biochemical Modification of Conductive Protein Fibers for the Next-Generation Bioelectronics

 The Master thesis project aims to develop a novel biochemical approaches for the manipulation of conductive cable bacteria fibers. The secret of cable bacteria conductivity is in their periplasmic fibers, which are highly conductive. These fibers should be extracted from the cable bacteria for further processing. Electrical and electrochemical characterizations of these fibers will be performed to investigate their intrinsic properties. Furthermore, chemical cell fixation and fluorescence in situ hybridization protocols will be established and optimized to examine the internal structures of the fibers. In addition, the biocompatibility and long term stability under cell culture conditions will be evaluated. On the long term, these fibers will be used to decorate microelectrodes for the recording of action potentials from electrogenic cells.

Your tasks will include:

  • Performing and optimizing protocols for the chemical extraction of biological fibers and fixation of bacterial cells connected to microelectrodes
  • Modification of microcelectrode surfaces with conducting protein fibers and their morphological characterization
  • Electrical and electrochemical characterization of native and engineered conductive protein fibers
  • Testing the stability and biocompatibility of the protein fibers for electrogenic cells
  • Establishing and maintaining cell cultures
  • Communication with other scientists from the EU project
