Single Chip Probe for High Resolution Magic Angle Coil Spinning Nmr of Biological Samples
نویسندگان
چکیده
We report a single-chip probe for “magic angle coil spinning”-MACS nuclear magnetic resonance (NMR) spectroscopy. The probe consists in a wirebonded microcoil integrated with an on-chip interdigitated capacitor. This LC-circuit is resonant at 500 MHz (H Larmor frequency at 11.7 T) enabling wireless inductive coupling of the NMR signal and spinning for high resolution NMR. We demonstrate stable spinning up to 110 Hz of the probe containing 330 nl water sample. The probe successfully withstands the large centrifugal forces as well as the eddy current heating. We prove increased spectral resolution down to 5.6 Hz (11 ppb at 500 MHz) as an effect of spinning at 110 Hz.

This article describes the development and testing of the first automatically microfabricated probes to be used in conjunction with the magic angle coil spinning (MACS) NMR technique. NMR spectroscopy is a versatile technique for a large range of applications, but its intrinsically low sensitivity poses significant difficulties in analyzing mass- and volume-limited samples. The combination of m...

We report the construction of a dual-channel microcoil nuclear magnetic resonance probehead allowing magic-angle spinning for mass-limited samples. With coils down to 235 mum inner diameter, this allows high-resolution solid-state NMR spectra to be obtained for amounts of materials of a few nanoliters. This is demonstrated by the carbon-13 spectrum of a tripeptide and a single silk rod, prepare...

Ultrafast high-resolution magic-angle-spinning NMR spectroscopy.
We demonstrate the acquisition of ultrafast 2D NMR spectra of semi-solid samples, with a high-resolution magic-angle-spinning setup. Using a recent double-quantum NMR pulse sequence in optimised synchronisation conditions, high-quality 2D spectra can be recorded for a sample under magic-angle spinning. An illustration is given with a semi-solid sample of banana pulp.
متن کاملSolid State NMR Probe Design
The majority of solids NMR experiments today are driven by biological applications in rigid macromolecules, where even the most advanced liquids methods are limited by the spectral resolution they can achieve. Obtaining detailed structural information from NMR of solid samples is often more technically demanding than for liquids because of the absence of molecular tumbling in solids to average ...
