Abstract

Modern NMR spectroscopy has reached an unprecedented level of sophistication in the determination of biomolecular structure and dynamics at atomic resolution in liquids. However, the sensitivity of this technique is still too low to solve a variety of cutting-edge biological problems in solution, especially those that involve viscous samples, very large biomolecules or aggregation-prone systems that need to be kept at low concentration. Despite the challenges, a variety of efforts have been carried out over the years to increase sensitivity of NMR spectroscopy in liquids. This review discusses basic concepts, recent developments and future opportunities in this exciting area of research.

摘要

现代核磁共振光谱学在测定液体中生物分子的原子分辨率结构和动力学方面已达到了前所未有的复杂程度。然而,该技术的灵敏度仍然过低,无法解决溶液中的各种前沿生物学问题,尤其是那些涉及粘性样品、非常大的生物分子或需要保持低浓度的易聚集体系的问题。尽管存在挑战,但多年来人们已经做出了各种努力来提高液体核磁共振光谱学的灵敏度。本综述讨论了这一令人兴奋的研究领域的基本概念、最新进展和未来机遇。
