Biomaterials
In the field of life science the possibility of imaging molecular ions is of importance.
The example shows a SIMS image of a placenta cell prepared on a silicon wafer.
The separation of the amino acid serine and the lecithin into different areas is clearly indicated by the overlay image on the right.
The sodium originates from the solution out of which the cell was prepared.
