PhD Student (m/f/d) 80 % Optimization of Carbon Electrode Interfaces for Reagent-Free Electrochemical Detection at the Point of Need In the Electrochemical Biosensors Group
Part-time position (80 %), Start-date: At the earliest possible date
For a research project in collaboration with academic and industrial partners, we are looking for a. PhD Student (m/f/d) 80 % Optimization of Carbon Electrode Interfaces for Reagent-Free Electrochemical Detection at the Point of Need In the Electrochemical Biosensors Group .
We are seeking a highly motivated PhD student to contribute to the development of robust carbon electrode interfaces for electrochemical multi-analyte detection in human body fluids. The project combines fundamental surface engineering with translational biosensor development in a highly interdisciplinary research environment.
You will work on the optimization and scalable implementation of biofunctionalization strategies to enhance the robustness, and analytical performance of electrochemical biosensors. A key focus will be the reduction of biofouling and the improvement of signal quality in complex biological matrices, with the aim of enabling reliable sample-to-answer solutions for future diagnostic applications.
Your task:
- Develop advanced electrode functionalization strategies, including tailored anti-biofouling surface modifications.
- Establish scalable DNA-based biofunctionalization of electrodes.
- Investigate multiplexing strategies for molecular isothermal and aptamer-based detection.
- Integrate molecular assays into sample-to-answer cartridges.
- Analyze and process data to reduce interference from complex biological matrices.
Your profile:
- Degree (Master of Science or equivalent) in chemistry, biochemistry, biophysics or related discipline.
- Knowledge of electrochemical methods such as cyclic voltammetry and SWV is an advantage.
- Experience with surface chemistry on gold or carbon, and simple organic syntheses, is an asset.
- Structured, independent, and meticulous working style with strong planning and documentation skills.
- Curiosity to learn new methods and contribute to a multidisciplinary team.
- Entrepreneurial mindset and interest in spin-off formation are an asset.
We offer:
- An attractive position in a modern, well-equipped, and industry-oriented research institute, offering exciting insights into medical device research and development.
- Close scientific supervision and comprehensive onboarding into the research topic.
- A fixed-term position for 2 years, with the possibility of extension.
