Periodic array-based substrates for surface-enhanced infrared spectroscopy

Nanophotonics, 2018
At the beginning of the 1980s, the first reports of surface-enhanced infrared spectroscopy (SEIRS) surfaced. Probably due to signal-enhancement factors of only 101 to 103, which are modest compared to those of surface-enhanced Raman spectroscopy (SERS ...

Intermolecular Interactions as Driving Force of Increasing Multiphoton Absorption in a Perylene Diimide‐Based Coordination Polymer

Advanced Functional Materials, EarlyView.
This study uncovers the unexplored role of intermolecular interactions in multiphoton absorption in coordination polymers. By analyzing [Zn2tpda(DMA)2(DMF)0.3], it shows how the electronic coupling of the chromophores and confinement in the MOF enhance two‐and three‐photon absorption.

Femtosecond infrared spectroscopy of channelrhodopsin-1 chromophore isomerization

Structural Dynamics, 2016
Vibrational dynamics of the retinal all-trans to 13-cis photoisomerization in channelrhodopsin-1 from Chlamydomonas augustae (CaChR1) was investigated by femtosecond visible pump mid-IR probe spectroscopy.

Imaging of Lipid Droplets in Living Cells and Mice with Metabolic Dysfunction‐Associated Steatotic Liver Disease via a Galactose‐Modified Supramolecular Near‐Infrared Fluorescent Glycoprobe

Advanced Functional Materials, EarlyView.
A galactose‐modified supramolecular near‐infrared (NIR) glycoprobe, TCF‐FBN@Gal‐BSA, enables targeted delivery to the liver through the asialoglycoprotein receptor (ASGPR) and facilitates liver‐targeting fluorescence visualization of lipid droplets (LDs) in metabolic dysfunction‐associated steatotic liver disease (MASLD) mice.

NanoMOF‐Based Multilevel Anti‐Counterfeiting by a Combination of Visible and Invisible Photoluminescence and Conductivity

Advanced Functional Materials, EarlyView.
This study presents novel anti‐counterfeiting tags with multilevel security features that utilize additional disguise features. They combine luminescent nanosized Ln‐MOFs with conductive polymers to multifunctional mixed‐matrix membranes and powder composites. The materials exhibit visible/NIR emission and matrix‐based conductivity even as black bodies.

Synchrotron Radiation for Quantum Technology

Advanced Functional Materials, EarlyView.
Materials and interfaces underpin quantum technologies, with synchrotron and FEL methods key to understanding and optimizing them. Advances span superconducting and semiconducting qubits, 2D materials, and topological systems, where strain, defects, and interfaces govern performance.
