Tensile Expansion Mass Spectrometry for single cell metabolomics imaging

Jason A. Guerrero, Ethan A. Older, Marouen Zammali…·Laura M. Sanchez

Tensile stretching of live, unfixed OVCAR8 cells on a fibronectin-functionalized double-network hydrogel expands them about 1.7x linearly, enabling single-cell MALDI metabolite imaging on unmodified commercial instruments.
