The apoplasmic charater of ectomycorrhizal roots of Larix seedlings infected with Paxillus involutus was examined using the cathnic colloidal gold. The result showed the density and distribution of anionic binding sites were different in sheath and Hartig net. The negative charger in the outer part of the sheath was slightly low. It increased graduately from outer to inter sheath. The negative charger density rised higher in the inter part of the sheath and then decreased graduatedly from the sheath to Hartig net. This may be related to nutrient uptake and atransport in ectomycorrhizal roots.

The humidity resistance and the sensitivity to chemical warfare agents simulants of the tuned films were also investigated.Self-assembled LBL polyaniline films were prepared from aniline monomers by in situ polymerization and the mechanism of film formation was discussed. It was proposed that the self-assembly of polyaniline occurred through the quick absorption of aniline monomer cations or aniline monomer cation radicals on the glass surfaces by electrostatic attractions to form homogeneous polymerization centers, then increased gradually by the way of upright to the glass supports for extensity, leading to the polyaniline chain growth. The polyaniline was doped under acidic condition to absorb anionic polyelectrolyte, such as sodium polystyrene sulfonate based on the electrostatic force, or to adsorb polymer based on hydrogen-bonding interactions, for example Polyvinyl Alcohol, and then recycled to fabricate_n or_n self-assembled multilayer films.
