What is it about?
We have provided the conditions for fabricating sub-10 nm nanopipettes with good reproducibility and procedures for their geometrical characterization by TEM. The TEM imaging following our methods enables quick assessment of tip geometry for many nanopipettes, without deformation of the tip by electron beam-generating heat.

Why is it important?
Here, we provide methods for preparing TEM specimens that do not cause deformation of sub-10 nm diameter nanopipettes.
Perspectives
Our methods will assist and facilitate the production of smaller nanopipettes and thereby contribute to improving various nanopipette applications in sensing and imaging
