Abstract: A highly conductive nanocomposite material. The material is particularly useful for serial block-face scanning electron microscopy. A polymer resin of the invention is stabilized for conductivity with a conductivity stabilizer selected from one of multi-walled carbon nanotubes, Perylene dianhydride, Hemoglobin, Epoxy-Corannulene, and Bovine Serium Albumin (BSA). The conductivity stabilizer is monodisperse in preferred resins. A preferred nanocomposite material includes a base component of a curable resin, a curing agent or hardener and monomers of carbon containing networks of sp2 hybridized carbon atoms that are dispersed in the base resin. In preferred embodiment, tissue samples are within the resin. Highly effective serial block face scanning electroscopy techniques are provided.
