Superluminescence from an optically pumped molecular tunneling junction by injection of plasmon induced hot electrons

Beilstein Journal of Nanotechnology, 2015
Here, we demonstrate a bias-driven superluminescent point light-source based on an optically pumped molecular junction (gold substrate/self-assembled molecular monolayer/gold tip) of a scanning tunneling microscope, operating at ambient conditions and ...

Detachment, Futile Cycling and Nucleotide Pocket Collapse in Myosin-V Stepping

, 2015
Myosin-V is a highly processive dimeric protein that walks with 36nm steps along actin tracks, powered by coordinated ATP hydrolysis reactions in the two myosin heads.

Photoluminescence emission and Raman enhancement in TERS: an experimental and analytic revisiting

Nanophotonics
An analytic model is used to calculate the Raman and fluorescence enhancement of a molecule in between two closely spaced gold nanospheres. Instead of using the conventional approach that only the dipolar plasmonic mode is considered, we calculate the ...

LILBID laser dissociation curves: a mass spectrometry-based method for the quantitative assessment of dsDNA binding affinities

Scientific Reports, 2020
One current goal in native mass spectrometry is the assignment of binding affinities to noncovalent complexes. Here we introduce a novel implementation of the existing laser-induced liquid bead ion desorption (LILBID) mass spectrometry method: this new ...

Ultrafast carbon monoxide photolysis and heme spin-crossover in myoglobin via nonadiabatic quantum dynamics

Nature Communications, 2018
Myoglobin bound to carbon monoxide undergoes an ultrafast light-induced reaction, which ends up in a photolyzed carbon monoxide and a spin transition of the iron center.

Operando Investigations of Rare-Earth Oxycarbonate CO₂ Sensors

Proceedings, 2018
In this work, we have succeeded in synthesizing monoclinic and hexagonal La2O2CO3 using two different routes and revealed that both of them are sensitive to CO2 to the same degree.
