Artikel des Tages: Slow magic-angle coil spinning: A high-sensitivity and high-resolution NMR strategy for microscopic biological specimens

Der heutige Artikel des Tages widmet sich einer eher technischen Fragestellung.
Erschienen ist er im Februar 2010 in der Zeitschrift Magnetic Resonance in Medicine, Vol. 63, Teil 2, Seiten 269-274.

High-resolution magic-angle spinning has become a valuable tool to study biologic samples; however, there are only a few high-resolution magic-angle spinning methodologies that have been explored specifically to deal with small semisolid biomaterials such as tissues. Here, we report a novel high-resolution 1H NMR spectroscopic approach using magic-angle coil spinning. We demonstrate its potential for intact tissues by combining a resonant microcoil with a large-volume commercial magic-angle spinning rotor, where the microcoil offers incredible sensitivity and the large-volume magic-angle spinning rotor provides stable slow magic-angle spinning. This approach provides high-resolution spectra with high sensitivity and the preservation of living biologic specimens for an accurate chemical analysis.
