NanoSuit® Aqueous Solution for SEM

Forms a thin, conductive, moisture barrier between specimens and a vacuum environment

Taking electron microscope images of biological objects in their natural state

What is the NanoSuit®

  • A novel technology which enables us to observe cells, microorganisms, etc. in a living state using scanning electron microscopy (SEM).
  • NanoSuit forms a very thin barrier layer on the surface of an object and the barrier layer holds moisture in the object under vacuum condition in electron microscopy. Also, the barrier layer is electrically conductive.
  • Therefore, NanoSuit makes it possible to observe biological objects with their natural image texture.
  • NanoSuit is very easy to use. Only dropping the NanoSuit solution onto the objects, then you can observe the objects using SEM. (You don't need any other fixation procedures.)


Inventor Professor Takahiko Hariyama tried to observe various microorganisms using SEM, but almost all organisms died due to losing moisture under the vacuum condition in the electron microscopy.

However, he discovered a kind of fly larva was able to keep alive under the vacuum condition.

Prof. Hariyama investigated that phenomenon and revealed that a very thin barrier layer was formed on the surface of the larva by electron beam irradiation. The barrier layer held moisture and kept the larva alive.

Hariyama and his colleagues had tried to mimic this phenomenon artificially and invented "NanoSuit" technology.


The "NanoSuit"

  • Aqueous solution of the biocompatible polymer. (biologically safe material)
  • Just drop onto the objects.
  • Polymerize by electron beam or plasma irradiation, then a thin barrier layer is formed on the surface of the objects.
  • The barrier layer holds moisture contained in the objects and its conductivity provides clear SEM images.
