«Proton Coupled Electron Transfer dynamics observed
over 8 orders of magnitude in time»

Charge transfer mechanisms lay at the heart of chemistry and biochemistry. Proton coupled electron transfers (PCET) are central in biological processes such as photosynthesis and in the respiratory chain, where they mediate long range charge transfers. These mechanisms are normally difficult to harness experimentally due to the intrinsic complexity of the associated biological systems. Metal-peptide cations experience both electron and proton transfers upon photo-excitation, proving an amenable model system to study PCET.

«Spooky spectroscopy»

In a perspective article of Nature Photonics (Vol. 10 No 2, 77 – 79, (2016) [DOI: 10.1038/nphoton.2015.267]), Yaron Silberberg and Jean-Pierre Wolf explore the recent possibilities offered by quantum spectroscopy for sensing. Quantum interference pathways using ultrashort shaped laser pulses and entangled photons are both considered for opening new applications such as label free protein identification and atmospheric trace gas detection”

SECOND ERC GRANT !


Prof. Wolf, who was awarded an ERC Advanced Grant in 2011, is now awarded a ERC Proof of Concept grant (http://erc.europa.eu/erc-funded-projects). The project aims at further developing the BioBox, which successfully identified Pollens in the countryside and marine aerosol during the Planet Solar-Deepwater campaign, in order to detect and identify bacteria in air. The new system will then be tested in actual conditions, namely operation rooms and clean rooms for immunodeficient patients at the HUG (Hopital Universitaire de Geneve). This approach would provide a quantitative probability of detecting a specific pathogen (for instance multiple resistant bacteria such as MRSA) to the healthcare and safety personal
