Quantifying the Limits of Detection of Surface-Enhanced Infrared Spectroscopy with Grating Order-Coupled Nanogap Antennas

Hatice Altug, Andreas Tittl, Aurélian Michel John-Herpin

Infrared spectroscopy is widely used for biomolecular studies, but struggles when investigating minute quantities of analytes due to the mismatch between vibrational cross sections and IR wavelengths. It is therefore beneficial to enhance absorption signal ...

High-Contrast Infrared Absorption Spectroscopy via Mass-Produced Coaxial Zero-Mode Resonators with Sub-10 nm Gaps

Hatice Altug, Aurélian Michel John-Herpin, Sunghwan Kim

We present a wafer-scale array of resonant coaxial nanoapertures as a practical platform for surface-enhanced infrared absorption spectroscopy (SEIRA). Coaxial nanoapertures with sub-10 nm gaps are fabricated via photolithography, atomic layer deposition o ...

Resolving molecule-specific information in dynamic lipid membrane processes with multi-resonant infrared metasurfaces

Hilal Lashuel, Daniel Rodrigo Lopez, Hatice Altug, Nadine Aït Bouziad, Andreas Tittl, Aurélian Michel John-Herpin, Odeta Limaj, Christopher David Kelly

A multitude of biological processes are enabled by complex interactions between lipid membranes and proteins. To understand such dynamic processes, it is crucial to differentiate the constituent biomolecular species and track their individual time evolutio ...
