In this review, recent progress in understanding the direct effects of radiation on the structure
and stability of collagen, the most abundant protein in the human body, and other proteins is …

Maintaining the protein high-order structures and interactions during the transition from
aqueous solution to gas phase is essential to the structural analysis of native mass …

Photon activation of ions in the visible and ultraviolet range attracts a growing interest, partly
for its promising applications in tandem mass spectrometry. However, this task is not trivial …

As great differences were observed in the amount of α-amylase in human saliva, there is a
need to better understand the effect of this protein alone or in mixture with mucin on aroma …

Site-selective dissociation induced by core photoexcitation of biomolecules is of key
importance for the understanding of radiation damage processes and dynamics and for its …

Near-edge X-ray absorption mass spectrometry (NEXAMS) around the nitrogen and oxygen
K-edges was employed on gas-phase peptides to probe the electronic transitions related to …

Preservation of protein conformation upon transfer into the gas phase is key for structure
determination of free single molecules, for example using X‐ray free‐electron lasers. In the …

We present experiments where extreme ultraviolet femtosecond light pulses are used to
photoexcite large molecular ions at high internal energy. This is done by combining an …

Carbohydrates have a wide variety of structures whose complexity and heterogeneity
challenge the field of analytical chemistry. Tandem mass spectrometry, with its remarkable …

Action spectroscopy of protonated substance P, a model undecapeptide, has been probed
from 5.2 eV to 20 eV. For photon energy above the ionization threshold measured at …
