DOI: 10.1016/j.bpj.2017.07.031
Abstract: The radical-pair mechanism has been put forward as the basis of the magnetic compass sense of migratory birds. Some of the strongest supporting evidence has come from behavioral experiments in which birds exposed to weak… read more here.

DOI: 10.1016/j.jmmm.2019.01.099
Abstract: Abstract In this paper, we used anti-cancer flutamide (FM) as a radical pair-forming drug to investigate whether magnetic fields can control a liposomal drug release through differences in the physical properties of biomembranes. Irradiations of… read more here.

DOI: 10.1021/acscatal.8b00120
Abstract: Coenzyme B12 (adenosylcobalamin = AdoCbl)-dependent enzymes catalyze complex molecular transformations by employing radical chemistry. The initial step in the native catalytic cycle, upon substrate binding, involves homolytic cleavage of the Co–C bond of AdoCbl to… read more here.

DOI: 10.1021/jacs.1c13108
Abstract: Activation of inert molecules like CO2 is often mediated by cooperative chemistry between two reactive sites within a catalytic assembly, the most common form of which is Lewis acid/base bifunctionality observed in both natural metalloenzymes… read more here.

DOI: 10.1021/jacs.3c01196
Abstract: The generally proposed mechanism for the reaction between non-heme Fe-oxo complexes and alkane C-H bonds involves a hydrogen atom transfer (HAT) reaction step with a radical pair intermediate that then has competitive radical rebound, dissociation,… read more here.

DOI: 10.1038/s41467-019-11655-2
Abstract: The fact that many animals, including migratory birds, use the Earth’s magnetic field for orientation and compass-navigation is fascinating and puzzling in equal measure. The physical origin of these phenomena has not yet been fully… read more here.
