IMT 14-20 Master Thesis: Development of an Optofluidic Platform to study phototaxis in Microorganisms

Karlsruhe Institute of Technology (KIT) – The Research University in the Helmholtz Association creates and imparts knowledge for the society and the environment. It is our goal to make significant contributions to mastering the global challenges of mankind in the fields of energy, mobility, and information. For this, about 9300 employees of KIT cooperate in a broad range of disciplines in research, academic education, and innovation.

Organizational unit

Institute of Microstructure Technology (IMT)

Job description

Are you interested choreographing the orientation and position of light sensitive microorganisms to unravel their movement patterns and optical properties? In this project, we aim to develop an optoelectronic microfluidic chip that is capable of displacing and trapping bacteria cells using forces generated by electric fields. The trapped cells will then be investigated using optical waveguides under a microscopic platform.

The specific tasks within the project will be: (i) design and simulation using COMSOL of devices; (ii) cell handling and testing; (iii) fabrication and microscopic testing of cells in microfluidic chambers; (iv) design and fabrication of optoelectronics circuit boards.

You will be integrated in a larger team within the SPA-Lab. Within this project, you will use the infrastructure existent at the Institute of Microstructure Technology (IMT), i.e., microfabrication facilities and micro-characterization equipment. This is a complete project, offering the possibility to fabricate and test the devices, giving you the opportunity to co-author conference and/or journal publications.
