NMR

A new magnetic resonance method can make specific areas of molecules visible while suppressing disturbing background signals during the measurement. The method, developed by Stefan Glöggler and his team, shall in future also be used for medical diagnostics using magnetic resonance imaging (MRI). more

The number is gigantic: In medical diagnostics, about 100 million examinations are carried out with magnetic resonance imaging every year – and every scanner worldwide uses the technology developed by Jens Frahm and his team at the MPI for Biophysical Chemistry. For his achievements, the physicist has now been awarded the Werner von Siemens Ring, one of the most important German technology prizes. more

A research team headed by Marina Bennati at the MPI for Biophysical Chemistry, together with colleagues at the University of Florence (Italy), has shown that ¹³C NMR spectroscopy signals can be strongly enhanced in solution by resonant microwave irradiation of a nitroxide organic radical used as polarizer for ¹³C nuclei. The new method shows up to 1000-fold improvements in sensitivity and promises to study small molecules and metabolites in much greater detail. more
