PhD: 3D carbon micro‑ and nanoelectrodes for biomarker detection – DTU

Are you interested in biomedical technology and how microdevices could improve diagnostics and patient monitoring? Would you like to contribute to the development of novel strategies and devices for electrochemical detection of biomarkers and pathogens by applying micro- and nanoengineering skills? 

Here, you can join an international research team to do exactly this! In the CAMINO project, we are looking for a talented PhD candidate that can establish novel processes for fabrication of 3D pyrolytic carbon nano- and microelectrodes and integrate them into sensor platforms for electrochemical detection. The aim is to achieve nanogap electrodes suitable for redox amplification and 3D microelectrodes for bacteria sorting by dielectrophoresis. In this project you will work in close collaboration with researchers at Tecnológico (TEC) de Monterrey, Mexico.

You will be based at DTU Nanolab, where we conduct cross-disciplinary research and apply micro- and nanotechnology to a wide range of scientific disciplines and applications. The Biomaterial Microsystems group is a highly ambitious group, pursuing research on microfabrication of polymer and carbon structures and devices for biomedical applications, bioelectrochemistry and sustainable energy. The position includes research stays at TEC with focus on sensor design and application.

Responsibilities and qualifications

Biomedical technology for health monitoring and point-of-care testing for quality-of-life improvement as well as disease monitoring and prevention has seen widespread adoption by our societies. The key challenge remains to detect relevant analytes at very low concentrations in highly complex and interfering media such as blood, urine or saliva. In CAMINO, we will design, fabricate and evaluate electroanalytical sensor platforms for biomarker detection exploring redox amplification and dielectrophoresis. Our hypothesis is that specifically designed and optimized 3D carbon micro- and nanoelectrodes fabricated at DTU Nanolab will enable lowering limit of detection (LOD) for electrochemical sensing in biorelevant fluids at TEC. This will allow electroanalytical point-of-care methods to replace laboratory assays where currently expensive optical methods or PCR are employed.

Your main contribution in this project will be the design and microfabrication of the 3D carbon electrodes, exploring processes such as thin film deposition, photolithography, plasma etching and pyrolysis in the cleanroom facilities at DTU Nanolab. Furthermore, you will characterize the carbon materials and evaluate the electrochemical properties of the 3D electrodes. In collaboration with two PhD students at TEC you will evaluate the novel sensor platforms for biomarker detection and dielectrophoresis.Your primary tasks will be to:

• plan and execute experimental research
• design, fabricate and optimize 3D carbon micro- and nanoelectrodes for dielectrophoresis and redox amplification
• evaluate material properties and electrochemical performance of the 3D electrodes
• integrate the 3D electrodes in electrochemical sensor platforms for detection of biomarkers and pathogens
• assist in preparation and testing of the platforms at the partner institution
• collaborate with an interdisciplinary research team in a focused scientific effort
• contribute as teaching assistant at DTU Nanolab and supervise BSc and MSc student projects

You must have a two-year master's degree (120 ECTS points) or a similar degree with an academic level equivalent to a two-year master's degree in micro- or nanoengineering, mechanical engineering, biomedical engineering or similar. Experience with cleanroom microfabrication processes is highly beneficial. You are expected to have a keen interest in biomedical microsystems and the ability to interact with researchers in a very interdisciplinary environment. Excellent English language skills are decisive to be considered for the scholarship.

Approval and Enrolment The scholarship for the PhD degree is subject to academic approval, and the candidate will be enrolled in one of the general degree programmes at DTU.
