Summary on Grant Application Form
Magnetic fields can influence the course of chemical reactions proceeding via radical pair intermediates, altering the ratio of the yields of potentially hazardous free radicals relative to diamagnetic recombination product. Despite growing anxiety about the possibly damaging effects of non-ionizing electromagnetic radiation on living tissue very little attention has been devoted to the investigation of magnetic field effects on biological systems. The proposed research will investigate radical recombination reactions in membranes under the influence of both oscillating and static magnetic fields with a particular focus on the effects of weak magnetic fields (ie, fields similar to that of the Earth). Two new experiments are to be designed and a new theoretical approach combining the simultaneous influence of weak static and time dependent magnetic fields on a spin system will be provided.Additionally, prompted by theoretical predictions, the orientation dependence of these magnetic field effects in rigid radical pair systems (eg, the photosynthetic reactions centre) will be studied and hence the possibility of a link between these effects and animal navigation phenomena will be determined.Furthermore, the effects of magnetic fields on the convection of paramagnetic species in chemical and biological tissue will be studied which will provide an alternative mechanism for the above phenomena.Finally, following my long standing interest in magnetic resonance, Electron Paramagnetic Resonance (EPR) will be used to investigate the processes of protein folding on spin-labelled samples in real time.
