Job description

Project background

Multiplexed biosensing technologies can bring an important impact to the medical practice reflecting more accurately the health status and favouring a quicker, more accurate, and early detection of a disease by maximizing the amount of information that can be obtained.

The project aims to develop a new biosensing technology based on micro/nano-systems for performing reliable and efficient monitoring of multiple key biological biomarkers of the immune system linked with health conditions such as cancer.

The PhD position will be funded by the Special Research Fund (BOF) of Ghent University. The position is located within the Centre for Microsystems Technology (CMST) at the Department of Electronics and Information Systems (ELIS) of the Faculty of Engineering and Architecture. CMST is an imec associated research lab at the Ghent university focusing on smart microsystems integration and design.

Your PhD Topic – Development of a multiplexed nano-bio-sensing system for in-parallel monitoring of multiple health biomarkers.

The doctoral student will be in charge of the fabrication process of nanodevices in the state-of-the art cleanroom at Ghent University, surface bio-functionalization of the devices with receptor molecules (antibodies, DNA aptamers) and electrical characterization of the devices prior and after the surface treatment. He/she will be in charge of the integration of the biosensing elements with supporting readout electronics and responsible for the implementation and validation of the complete system for biosensing applications. Specifically, he/she will conduct biosensing experiments for the detection and the monitoring of the concentration in interstitial fluid and/or blood of multiple biomarkers (cancer markers, inflammatory markers). One of the main aims of the research will be to optimize the bio-sensors considering the aspects of high selectivity, high sensitivity, low false positive and false negative rates as well as to investigate the interrelation of the biomarkers under study in cases of cancer.

A summary of topics characterizing this PhD:

• Fabrication and testing of nanodevices
• Surface bio-functionalization of nanodevices
• Biosensing experiments: Measuring the concentration of biomarkers in interstitial fluid/blood
• Electrical (I-V measurements) and morphological (SEM, AFM) characterization of micro/nano-fabricated devices and biosensing devices
• Design and develop the electronic readout circuitry for the sensors
• Multidisciplinary research
• Micro- and nanotechnology in a cleanroom environment
• Realization of a complete multiplexed biosensing system
  
  

The doctoral project will combine micro/nanofabrication with biosensor research, basic biochemistry, electronics and microscopy to generate truly interdisciplinary doctoral research scientist. The result from the doctoral project will be a model multi-panel diagnostic platform paving the way for an in-parallel analysis of a large sample throughput.
