Articles

We present an article about the hyperpolarization of 13C labeled metabolites, especially pyruvic acid, using dynamic nuclear polarization (DNP) that allows real-time magnetic resonance spectroscopy.

Dynamic Nuclear Polarization (DNP) is a phenomenon by which high spin polarization, typically derived from a bath of free radical electrons, is transferred to a nuclear spin bath, enhancing the difference between the nuclear energy levels and thereby producing dramatically enhanced NMR signals for detection.

Sigma-Aldrich.com presents an article concerning MRI/MRS and the use of isotopes in hyperpolarization.

Our team of scientists has experience in all areas of research including Life Science, Material Science, Chemical Synthesis, Chromatography, Analytical and many others.
