MSc thesis project proposal

Nanoparticle decoration of graphene for enhanced gas sensing

The unique properties of chemically-synthesized nanoparticles are out of reach for traditional top-down nanofabrication techniques alone. Systematic and reproducible harnessing of such properties calls for fabrication methods enabling a high degree of spatial nanoparticle organization and assembly yield. This is an essential prerequisite to tailor the integration of nanoscale components within substrates to build advanced nanoelectronic and optical devices. In particular, graphene-based sensing can be significantly enhanced by the controlled integration of nanoparticle arrays or monolayers.

Topographically-templated capillary assembly of nanoparticles is a simple and powerful technique that allows to selectively place single nanoparticles in targeted substrate locations pre-specified by local topographical features. Recent advances have shown the ultimate reach of the technique in terms of positional control, spatial selectivity and yield.

This project aims at decorating graphene substrates with precisely controlled nanoparticle arrays to enable the deployment of graphene-based gas sensors of enhanced sensitivity and selectivity.


This experimental project will involve:
• an initial extensive review of the related state-of-the-art;
• the design, assembly and testing of a flow coating setup for capillary nanoparticle deposition;
• the templating of graphene substrates with topographical or chemical patterns;
• the performance and characterisation of the capillary nanoparticle assembly process;
• comprehensive reporting of the full experimental work.


You are an ambitious hands-on master student from mechanical engineering, materials science or (applied) physics. You have good communication skills in English, you are independent and also a team player. The graduation project will have a total duration of 9 to 12 months.

If you are looking forward to working in a challenging atmosphere with highly skilled co-workers, then send us your CV!
