Sum-Frequency Scattering Spectroscopy Reveals the Charging Mechanism and Surface Structure of hBN Nanoflakes in Solution

Aleksandra Radenovic, Sylvie Roke, Li Zhang, Nathan Cyprien Arsène Ronceray, Benjamin Rehl

A molecular understanding of the interactions between two-dimensional (2D) layered materials and liquids is crucial for nanofluidics, catalysis, and solution-based 2D material processing. Among 2D materials, hexagonal boron nitride (hBN) has a number of ou ...

Wide-field fluorescence lifetime imaging of single molecules with a gated single-photon camera

Claudio Bruschini, Edoardo Charbon, Aleksandra Radenovic, Matteo Dal Peraro, Nathan Cyprien Arsène Ronceray

Fluorescence lifetime imaging microscopy (FLIM) is a powerful tool to discriminate fluorescent molecules or probe their nanoscale environment. Traditionally, FLIM uses time-correlated single-photon counting (TCSPC), which is precise but intrinsically low-t ...

Nanofluidic logic with mechano-ionic memristive switches

Andras Kis, Aleksandra Radenovic, Théo Denis Tobias Emmerich, Andrey Chernev, Nathan Cyprien Arsène Ronceray, Edoardo Lopriore, Yunfei Teng, Vasily Artemov

Neuromorphic systems are typically based on nanoscale electronic devices, but nature relies on ions for energy-efficient information processing. Nanofluidic memristive devices could thus potentially be used to construct electrolytic computers that mimic th ...

Label-Free Imaging of DNA Interactions with 2D Materials

Aleksandra Radenovic, Suliana Manley, Jenny Sülzle, Nathan Cyprien Arsène Ronceray, Yuta Shimoda, Eveline Simone Mayner, Wayne Yang Wen Wei

Two-dimensional (2D) materials offer potential as substrates for biosensing devices, as their properties can be engineered to tune interactions between the surface and biomolecules. Yet, not many methods can measure these interactions in a liquid environme ...

Monitoring Electrochemical Dynamics through Single-Molecule Imaging of hBN Surface Emitters in Organic Solvents

Aleksandra Radenovic, Martina Lihter, Nathan Cyprien Arsène Ronceray, Tzu-Heng Chen, Eveline Simone Mayner

Electrochemical techniques conventionally lack spatial resolution and average local information over an entire electrode. While advancements in spatial resolution have been made through scanning probe methods, monitoring dynamics over large areas is still ...

Optical imaging of molecules and their dynamics from surfaces to nanoscale confinement

Nathan Cyprien Arsène Ronceray

Molecular behavior can change dramatically at interfaces, and these changes become even more pronounced when molecules are confined within nanoscale dimensions. In living organisms, nanoscale channels play a crucial role in selectively transporting molecul ...

Synthesis of Fluorescent Cyclic Peptides via Gold(I)-Catalyzed Macrocyclization

Aleksandra Radenovic, Jérôme Waser, Beat Fierz, Xingyu Liu, Nathan Cyprien Arsène Ronceray, Wei Cai

Rapid and efficient cyclization methods that form structurally novel peptidic macrocycles are of high importance for medicinal chemistry. Herein, we report the first gold(I)-catalyzed macrocyclization of peptide-EBXs (ethynylbenziodoxolones) via C2-Trp C–H ...

Liquid-activated quantum emission from native hBN defects for nanofluidic sensing

Aleksandra Radenovic, Martina Lihter, Evgenii Glushkov, Nathan Cyprien Arsène Ronceray, Benjamin Rehl, Tzu-Heng Chen

Liquids confined down to the atomic scale can show radically new properties. However, only indirect and ensemble measurements operate in such extreme confinement, calling for novel optical approaches that enable direct imaging at the molecular level. Here ...
