- 37. A method for preparing cross-linked polyelectrolyte multilayers films, wherein said method comprises the reaction of complementary functional groups carboxylic groups and amino groups, present in the polymers that constitute the multilayer film, in the presence of a coupling agent, as to form amide bonds.

54. A method of coating a surface, comprising (1) sequentially depositing on a surface alternating layers of polyelectrolytes to provide a coated surface presenting complementary reactive groups:
- amino and carboxylic groups, wherein a first (or conversely second) polymer is a cationic polyelectrolyte and a second (or conversely first) polymer is an anionic polyelectrolyte, and (2) reacting said complementary reactive groups of the coated surface in the presence of a coupling agent, as to form amide bonds between said complementary reactive groups.
