||Primary source abstract: "Herein, [investigators] demonstrate the use of (19) F NMR [Nuclear magnetic resonance] spectroscopy to measure cytoplasmic viscosity and to characterize nonspecific protein-protein interactions in living Escherichia coli cells."
||P.6668 left column 3rd paragraph: "In E. coli, rotational diffusion was found to be 2–3 times slower than in pure water (primary source)." Primary source abstract: "[Investigators] found that sample inhomogeneity has a negligible effect on resonance broadening, the cytoplasmic viscosity is only about 2-3 times that of water, and ubiquitous transient weak protein-protein interactions in the cytosol play a significant role in governing the detection of proteins by using in-cell NMR spectroscopy."
