High-resolution elemental mapping of mitochondria using cryogenic EELS

news-medical.net

New cryogenic EELS techniques allow high-resolution elemental mapping of mitochondria, revealing calcium distribution. This advancement overcomes challenges with hydrated biological samples by using a sensitive K3 camera and GIF Continuum optics, enabling detailed analysis with low electron doses. The method successfully mapped calcium accumulation within mitochondria, a feat not possible with older detector technologies, offering new insights into cellular processes.
