Metal Fingerprints in Normal Cell States & Disease The field of metallomics utilises analytical tools to understand the biological roles of metals in biological space and time using elemental mass spectrometry. The characteristic metallomes change within the life span of individual cells and tissues. The corresponding metal profiles have significant value for fundamental scientific questions relating to the determination of cell fate and for distinguishing healthy and diseased states. The latest technologies in bioimaging can generate elemental profiles with cellular spatial resolution, which can be incorporated into multimodal imaging applications. We combine these profiles with other imaging techniques to characterise the biomolecules interacting with essential, non-essential, and toxic metal ions. Current research associated with LMF focuses on applications of metal profiling in cancer, diabetes and ageing, exploiting our unique Physiological Oxygen Laboratory to investigate metal profiles of cells grown under physiological oxygen concentrations. The LMF celebrated the King's Together Award with a virtual symposium with keynote speakers including Prof Sir Peter Ratcliffe FRS, 2019 Noble Laureate in Physiology or Medicine, and Prof Fiona Watt FRS, Executive Director, Medical Research Council. The Symposium abstract book and selected video recordings are available at: King's Together Symposium: 'Metal Fingerprints in Normal Cell States & Disease'
