Research

Overview

Peter’s research interests broadly lie in the development of novel synthetic and catalytic chemistry for application in biological systems. His current work focuses on the development of the SABRE technique for use in diagnostic imaging. This interdisciplinary task encompasses the design and synthesis of isotopically labelled (²H, ¹³C, ¹⁵N) substrates and the invention of novel ligands for the SABRE catalyst which coupled together give strong polarisation levels and long magnetic lifetimes. A number of analytical techniques, such as NMR and infra-red spectroscopy, mass spectrometry and X-ray crystallography, are used to develop structure-activity relationships that are used to evolve the SABRE process.

Optimised substrates and catalysts are investigated pre-clinically for their MRI detection. This information will be used to develop disease state diagnosis as the SABRE technique progresses towards medical applications.
