New Publication in Nanophotonics

Check out our latest publication: Photothermal Spectroscopy On-Chip Sensor for the Measurement of a PMMA Film using a Silicon Nitride Micro-Ring Resonator and an External Cavity Quantum Cascade Laser, led by Giovanna Ricchiuti and recently published in Nanophotonics De Gruyter. This paper introduces an innovative on-chip photothermal spectroscopy sensor designed for measuring thin films of polymethyl methacrylate (PMMA) utilizing a unique combination of a silicon nitride micro-ring resonator and an external cavity quantum cascade laser (EC-QCL).

This research, a product of collaborative efforts within the OPTAPHI double doctorate program, highlights the integration of analytical chemistry techniques from the CAVS Research Group at the Institute of Analytical Chemistry at Technische Universität Wien and advanced nanophotonic device fabrication skills from the Centre for Advanced Photonics & Process Analysis (CAPPA) group at Munster Technological University, in close collaboration with the Tyndall National Institute.

Special thanks to our co-authors, contributors, and especially to our supervisors, Dr. Liam O’Faolain and Prof. Dr. Bernhard Lendl, for their indispensable guidance. This achievement emphasizes the synergy between analytical chemistry and advanced nanophotonic device fabrication, paving the way for innovative online/in-line detection applications.

Through our research we contribute to the advancement of analytical sciences by developing novel analytical techniques and instrumentation mainly based on mid-IR laser spectroscopy. We also apply our technology to challenging problems in the fields of environmental and process analytical chemistry, material characterization as well as bio-medical diagnostics.

Hi, Sebastian!

Meet Sebastian, our new CAVS group member.

He did his Bachelor’s thesis on the analysis of polycyclic aromatic hydrocarbons in snow. This was followed by a Master’s degree focusing on applied physical and analytical chemistry, during which he developed a chromatographic system for in-situ monitoring of electrolyte degradation in Lithium-Ion batteries as part of his Diploma thesis.

Currently, Sebastian is working towards his PhD, focusing on the nanoscale chemical imaging of 2D materials within the scope of the TU-Dx doctoral college.

Welcome, Daniela!

Daniela obtained her Bachelor’s and Master’s degree in Technical Chemistry at TU Wien.

She started working in the group during her Master’s degree, but temporarily left to conduct her Master thesis on the assembly metal-phenolic networks at a faraway place (Tokyo University, Japan). Once she returned from that hot, humid and crowded place she rejoined the group and started her PhD.

Now that her detour into wet chemistry is finished, she is happy to work in the field of analytical chemistry again enjoying her time in the CAVS group.

Welcome Adea!

Adea obtained her Bachelor’s degree from TU Vienna after doing her thesis titled “Exploring the chiral possibilities of Au144(SR)60 nanoclusters” in the department of Materials Chemistry. She continued her master studies at TU Vienna, with a specialization in analytical and physical chemistry. After her research as a student assistant in the research group for Surface Analytics, Trace Analytics and Chemometry she joins our group to conduct her Master’s Thesis on the synthesis and characterization of mesoporous silica films used for analysis of biodiesel by ATR-Spectroscopy.

Welcome Lisa!

Lisa obtained her Bachelor’s degree at TU Wien, conducting her Bachelor Thesis at the Institute of Applied Synthetic Chemistry. She has been a student assistant within the CAVS group for the past year, providing support to other researchers in the field of liquid-phase spectroscopy.  

Now, upon her return from an exchange semester in Finland, she will continue her journey at the CAVS group by conducting her Master’s Thesis on QCL-IR absorption spectroscopy.
