Job description
Offer DescriptionThis 2-year post-doctoral project (starting from November 2024) aims to develop new optical detection chips based on plasmonic metasurfaces. Specifically, an original approach to achieve SPR detection will be developed by designing new nanomaterials with higher absorption efficiency. SPR detection substrates will be developed using nanofabrication techniques such as electron beam lithography. Ultimately, the goal of this project is to facilitate certain clinical applications, such as early disease prevention, using diagnostic tools based on the developed approach.Nanophotonic devices are widely used to study fundamental biological processes at the molecular level, all the way to quantum information processing. Among all approaches, surface plasmon resonance (SPR) sensors are of great interest due to their ability to detect biomolecules in real-time. In particular, SPR detection substrates based on plasmonic metasurface structures can surpass the detection limits of current metallic substrates [1-2]. The sub-nanometer tunability of plasmonic nanostructures allows for precise control of the resonance at the detection interface. Optimizing the coupling with the nanostructures leads to the exceptional property of generating a near-extinction of the reflected SPR signal, and this increased substrate absorption should provide an effective means of detecting small biomolecules in just 20 minutes with high signal-to-noise ratio.References:
