The ORNL team created a strain of the bacterium containing enough deuterium to make the cell structures essentially invisible to neutrons.
They then ensured that the lipid molecules within the membrane were made up entirely of two fatty acids containing specific proportions of deuterium and hydrogen.

They subsequently introduced the two fatty acids types with differing isotope ratios. The cell membrane was free to create and incorporate into its membrane lipid molecules from them, with each lipid type then containing a specific mix of the two isotopes. If the lipids were distributed randomly throughout the membrane, then the membrane would appear uniform when exposed to neutrons, akin to an optical background that was medium gray.
If, however, the lipids gathered with others of their type, the background would cease to be uniform and would show the equivalent of lighter and darker gray areas. This is in fact what the team found.

The grey patches detected using neutrons measured less than 40 nanometers across. The membrane itself was about 2.
The ORNL researchers stressed that their approach of creating internal contrast within living cells using isotopes held promise for other research as well, opening the technique of targeted deuteration to other physical techniques e. Our novel experimental approach opens up new areas of research.
