Conducting Polymers [discontinued]
Polypyrroles are used to form a thin molecular monolayer which is highly conductive (better than carbon); this is an ideal substrate for electron microscopy. To prepare the layer, unsubstituted pyrrole is mixed with one of the Nanoprobes surface active pyrroles (30DP or 30DOP) and applied to a water surface containing ferric chloride. The properties of the film are controlled using Langmuir-Blodgett techniques, and it is then used to coat grids for electron microscope observation (See: Simon, M. N., et al.: Proc. XIIth Int. Congress for Electr. Micr., San Francisco Press, Inc., San Francisco, CA, 1990; Vol. 1, pp. 290-291).
- Highly conductive
- Easily applied to grids.
- Hydrophilic for good protein binding.
