Common amino acids (AA) and their catabolic derivatives have been shown to constitute a class of biomarkers for early diagnosis of diseases such as cancers. In the frame of metabolomics techniques based on tandem mass spectrometry, different strategies can be employed for the separation step, in order to minimize the chemical noise and contribute to the resolution of isobaric or isomeric...
In addition to DNA/RNA and amino acids (proteins), flavins are an important class of biomolecules. Flavins (Fl) are derived from the 7,8-dimethyl-10-alkylisoalloxazine chromophore, which differ by their substituent R at the N10 position. The most important examples of the flavin family are lumichrome (LC, R=H), lumiflavin (LF, R=CH$_3$), riboflavin (RF, vitamin B2, R=ribityl), flavin...
Two-step photoexcitation of cryogenically cooled ion-hydrate clusters provides a way to obtain tag-free spectra of cold ions as well as a new window into the intracluster energy relaxation dynamics that drive predissociation. This is accomplished by recording the photodissociation spectra of individual excited vibrational levels using two-color, two-photon IR-IR photoexcitation. We first...
A Free Electron Laser (FEL) with high brightness, ultrafast laser pulses in the vacuum ultraviolet (VUV) wavelength region is an ideal light source for the excitation of valence electrons and the ionization of molecular systems with very high efficiency. It is quite helpful for studies of important dynamic processes in physical, chemical and biological systems. Dalian Coherent Light Source...
Chiral molecules play a fundamental role in a large variety of biological and chemical processes and their reactions may differ vastly for different enantiomers. Cold, polyatomic molecules offer a plethora of possibilities to test fundamental physics, for quantum control, and for studies of molecular structure, dynamics and cold chemistry. In our experiments we combine buffer gas cooling with...
