Fully funded PhD position on Colloidal plasmonic Metasurfaces for Single-Molecule Fluorescence Biosensing

The Department of Applied Physics and Science Education is a research-driven department housing high-quality educational programs all featuring strong connections between research and education. Our research is clustered in three focal areas: Fluids Bio and Soft Matter (FBSM); Plasmas and Beams (PB); and Nano Quantum and Photonics (NQP). Our shared ambition is to equip the next generation of engineers of the future with the knowledge and the skills they will need to impact science innovation and society from regional to global scales.

The Molecular Plasmonics group at the Eindhoven University of Technology has a PhD position in the field of metasurfaces for single-molecule biosensing. This project aims to develop a new generation of single-molecule sensors that exploit collective and localized resonances in metasurfaces to boost the sensitivity of plasmonic biosensors.

Introduction

Current workhorse techniques to detect and study single biomolecules rely on fluorescence microscopy. Recent advances in Zijlstras group used metallic nanoparticles to enhance the fluorescence intensity (link). This approach has given access for the first time to previously inaccessible microsecond dynamics (link). Further boosting the enhancement will require entirely novel designs that exhibit multiple resonances provided by e.g. plasmonic metasurfaces (link).

About this position

In this position you will leverage novel dielectric and plasmonic metasurface designs for single-molecule fluorescence sensing. You will perform colloidal assembly of plasmonic metasurfaces functionalize them with biomolecules such as DNA and then experimentally quantify the fluorescence enhancement mechanisms using single-molecule spectroscopy and super-resolution microscopy. This will allow you to answer questions like: how do we design a plasmonic metasurface to achieve record-breaking fluorescence brightness How do we probe these enhancement factors using single-molecule experiments How can we exploit these novel platforms for the next generation of single-molecule biosensors

The project will be supervised by Prof. Zijlstra (Molecular Plasmonics group) and co-supervised by Prof. Gomez Rivas (Surface Photonics group). You will closely collaborate with a team of PhD students across the two groups that work on metasurfaces for fluorescence manipulation.

About the groups

Both groups are part of the department of Applied Physics and Science Education. The molecular plasmonics group develops plasmonic and nanophotonic biosensors with single-molecule sensitivity. The nanoscale field confinement in resonant (e.g. plasmonic) nanoparticles is exploited to detect and study single molecules in real-time. The team is multidisciplinary and hosts physicists chemists and biomedical engineers that collaborate in a close-knit team. The lab hosts a range of state-of-the-art single-molecule microscopes in optical laboratories as well as wet-chemical labs for sample preparation. The group is part of a bigger research cluster focusing on optical sensing.

The surface photonics group investigates light-matter interaction in a broad range of frequencies from the visible to the THz. This interaction is enhanced by resonant structures such as metallic or dielectric nanoparticles and metasurfaces. The group is part of the research cluster Photonics and Semiconductor Nanophysics.
