Doctoral Thesis Defense in Materials Science and Modeling by Ms. Nidal EL BIYARI

Euromed University of Fes (UEMF) is pleased to inform the public of the

doctoral thesis defense in ” Materials Science and Modeling ”

The thesis defense will take place on Saturday January 18, 2025 at 10:00 at UEMF 

Location: Gallery/building 1

The thesis will be presented by Ms. Nidal EL BIYARI

Under the title:

“ Design, Modeling and Realization of Optofluidic Sensors Based on Surface Plasmon Resonance for Precision Sensing. ”

 

Abstract 

This thesis focuses on the development of high-performance optofluidic biosensors based on the surface plasmon resonance (SPR) phenomenon. A novel golden ratio approach was proposed to optimize the geometric properties of a gold-silver bimetallic configuration, achieving rapid optimization with enhanced sensitivity and resolution.

Additionally, a dual-mode plasmonic configuration combining guided modes in a dielectric waveguide and plasmonic modes on a gold film was studied. This configuration generates a detection mode (PIT) with high performance and a reference mode (TM1) to improve measurement reliability by minimizing false positives.

Finally, a new approach for microfluidic system fabrication using stereolithography additive manufacturing was developed, integrating real-time temperature control. This method improved the mechanical and structural properties of microfluidic chips, making them highly suitable for biosensing applications, as confirmed by microscopic analyses and mechanical tests.

Abstract 

This thesis focuses on the development of high-performance optofluidic biosensors based on the surface plasmon resonance (SPR) phenomenon. A new golden ratio approach was proposed to optimize the geometric properties of a gold-silver bimetallic configuration, allowing rapid optimization with increased sensitivity and resolution.

Furthermore, a bimodal plasmonic configuration combining guided modes in a dielectric waveguide and plasmonic modes on a gold film was studied. This configuration generates a high-performance detection mode (PIT) and a reference mode (TM1) to improve measurement reliability by minimizing false positives.

Finally, a new approach for manufacturing microfluidic systems using stereolithography additive manufacturing has been developed, integrating real-time temperature control. This method improved the mechanical and structural properties of microfluidic chips, making them well suited for biodetection applications, as confirmed by microscopic analyses and mechanical tests.
