Tuning of pH enables carbon-13 hyperpolarization of oxalates by SABRE
Autor: Soumya S. Roy, Wissam Iali, Gamal A. I. Moustafa, Malcolm H. Levitt
Nuclear spin hyperpolarization transforms typically weak NMR responses into strong signals paving the way for low-gamma nuclei detection within practical time-frames. SABRE (Signal Amplification by Reversible Exchange) is a particularly popular hyper

Publikováno v: Magnetic resonance in medicine. 88(1)
Enabling drug tracking (distribution/specific pathways) with magnetic resonance spectroscopy requires manipulation (via hyperpolarization) of spin state populations and targets with sufficiently long magnetic lifetimes to give the largest possible wi

Chapter 19. Long-lived Spin Order Coupled to SABRE
Autor: Soumya S. Roy
This chapter reports on the recent developments in the field of the Signal Amplification by Reversible Exchange (SABRE) nuclear spin hyperpolarisation technique in conjunction with the long-lived states (LLS) associated with nuclear spins. The underl

SABRE-Relay: A Versatile Route to Hyperpolarization
Autor: Soumya S, Roy, Kate M, Appleby, Elizabeth J, Fear, Simon B, Duckett
Publikováno v: The Journal of Physical Chemistry Letters
Signal Amplification by Reversible Exchange (SABRE) is used to switch on the latent singlet spin order of para-hydrogen (p-H2) so that it can hyperpolarize a substrate (sub = nicotinamide, nicotinate, niacin, pyrimidine, and pyrazine). The substrate

Direct enhancement of nitrogen-15 targets at high-field by fast ADAPT-SABRE
Autor: Soumya S, Roy, Gabriele, Stevanato, Peter J, Rayner, Simon B, Duckett
Publikováno v: Journal of Magnetic Resonance
Graphical abstract
Highlights • SABRE hyperpolarization is achieved at high field by the ADAPT pulse sequence. • A theoretical description of ADAPT-SABRE is linked to related methods for comparison. • ADAPT-SABRE achieves faster magnetizat

A Simple Route to Strong Carbon-13 NMR Signals Detectable for Several Minutes
Autor: Soumya S, Roy, Philip, Norcott, Peter J, Rayner, Gary G R, Green, Simon B, Duckett
Publikováno v: Chemistry (Weinheim an Der Bergstrasse, Germany)
Nuclear magnetic resonance (NMR) and magnetic resonance imaging (MRI) suffer from low sensitivity and limited nuclear spin memory lifetimes. Although hyperpolarization techniques increase sensitivity, there is also a desire to increase relaxation tim
