DESCRIPTION:There has been tremendous progress in fabrication of ultrathin
  films with nm precision as regards internal structure and roughness. The 
 versatility and modularity of film prepara-tion by alternating adsorption 
 of oppositely charged polyelectrolytes has then enabled to introduce multi
 functionality and stability into these films. This will be presented conce
 rn-ing the following issues:\n\n- Optically active polymers and nanopartic
 les will be introduced to assemble structures for photoelectric energy con
 version. - Insertion of suitable enzymes leads to amperometric biosensors.
  - Since the films can be made sensitive to changes in electrochemical env
 ironment or pH on may use them as anticorrosion coatings since they may re
 lease a corrosion inhibitor on demand. - Via metallic nanoparticles they m
 ay be made IR and heat sensitive. This can be made use of in controlled re
 lease from coatings\, e.g. to stimulate the growth of adjacent cells.
