We also discuss some technical features of this unique type of instrument and highlight some of the new advances which will likely become more widely used in the years to come. Keywords: bio-imaging; flood gun; helium-ion microscopy; high resolution; HIM; HIM-SIMS

• materials science, HIM is much less frequently used for imaging biological specimens. To date, 13 years after the first HIMs were commissioned, only about 70 papers (we are aware of 72) have been published which include HIM bio-imaging data for medical, geomicrobiological, or life sciences. Figure 1

• provides an overview of some key applications of HIM in bio-imaging together with an indication for the growth in the volume of literature which has been published in related fields. This steady growth of publications gives an indication for the increasing demand for HIM in biological applications and the
