“A Benzyl Alcohol Derivative of BDPA Radical for Fast Dissolution Dynamic Nuclear Polarization NMR Spectroscopy” by José Luis Muñoz Gómez, Eva Monteagudo, Vega Lloveras, Teodor Parella, Jaume Veciana and José Vidal Gancedo. Organic & Biomolecular Chemistry, 2015, 13:2689-2693. DOI: 10.1039/C4OB02356K

 

The synthesis, structural characterization and the successful application of a carbon centered radical derived from 1,3-bisdiphenylene-2-phenylallyl (BDPA), its benzyl alcohol derivative (BA-BDPA), as a polarizing agent for Dynamic Nuclear Polarization (DNP) are described.

What is DNP? Obtaining enhanced NMR signals for in-vitro and in-vivo applications

Methods & Applications, News from the SeRMN, , ,

Dynamic Nuclear Polarization is the method for obtaining strongly polarised nuclear spins, resulting in enhanced NMR signals for 13C and 15N nuclei in solution-state

Our NMR facility (SeRMN) has recently installed a HyperSense® (Oxford Instruments), a new instrument capable of delivering a huge sensitivity enhancement for your in-vitro and in-vivo applications allowing an easy and quick switching between both applications.

Liquid-state NMR spectroscopy is an important technique into a wide range of applications. However, it is limited by an intrinsically lack of sensitivity due to the low gyromagnetic ratio and natural abundance of the nuclei usually under study (13C, 15N, etc.) as compared with other analytical methods.
