We have succeeded in observing by NMR the wall of living bacterial cells. They were able to significantly increase the sensitivity of the NMR signal by a so-called hyperpolarization technique. In the presence of cells, the polarizing agent binds to the polymers of the wall and, under microwave irradiation, selectively amplifies the response of neighboring atomic nuclei. Such analyzes could contribute in particular to the development of new antibiotics.
