Development of stimuli-sensotive particles for tumour-selective targeting of TIM-3/Galectin-9
This PhD student position offers an exciting and innovative research project that aims to develop targeting of the TIM-3/Galectin-9 immune checkpoint for cancer immunotherapy and will result in a PhD thesis. Research by the UMCG has uncovered immunostimulatory effects of Gal-9 as well as direct anti-tumour cytotoxic activity of Gal-9. However, Gal-9 has pleiotropic functions and its therapeutic activity needs to be restricted to the tumour micro-environment. In this project, the development of tumour-selective nanoparticles with Gal9 and/or bispecific antibodies is pursued for cancer immunotherapy. This research project will end with a PhD thesis defense at the University of Groningen.

Keywords: Drug-delivery, Galectin-9, surface modification nanoparticles, microparticles, bioanalysis

Key Responsibilities:
- Development and characterization of tumor-selective nanoparticles by means of immobilizing antibodies on the particle surface or within porous particles
- Further optimization of the particle properties for long-term drug release and specific targeting of Galectin-9
- Development and optimization of polymeric scaffolds for realistic cell growth conditions
- Immobilization of selected proteins and antibodies on or within particles using layer-by-layer deposited polymer networks / hollow capsules
- Ensuring controlled delivery of particles to targets and a controlled release of immobilized active material on-target via suitable triggers (pH, etc.)
- Various encapsulation, release and surface modification activities
- Operation, optimization and further development of a bioanalysis platform that uses functionalized microparticles (model tumor cells) as sensors (Measurement principle: Whispering Gallery Modes)
- Optimization of the in vitro test conditions for a realistic simulation of the in vivo conditions
- Management, presentation and publication of research data


- You are in the first four years of your research career and not have a doctoral degree
- Residence duration in Germany does not exceed 12 months in total within the last 3 years
- MSc in chemistry, biochemistry,biotechnology
- Proven track record in one or more of the following fields:
Drug-delivery systems
Encapsulation and release of biomolecules
Surface modification and functionalization, nanoscale coatings, polymer systems
Nanoparticle / microparticle synthesis
Analysis of biomolecular interactions e.g. protein-protein, antibody-antigen
Biosensors and bioanalysis
- Collaboration skills, demonstrating agility and initiative. Ability to communicate fluently and effectively in English
- German language or the willingness to learn German is advantageous
