General description
Poly(diallyldimethylammonium chloride) is a water-soluble cationic polymer that can be prepared from diallyl dimethyl ammonium chloride via free radical polymerization.
It is a positively charged polyelectrolyte that finds application in various fields such as paper manufacturing, the mining industry, water treatment, protein immobilization, separation of biomolecules, removal of bacteria, flocculation of silica and latex particles, and nanocapsule shell formation.

There is great clinical interest in developing novel nanocarriers for hydrophobic cyanine dyes used as photosensitizing agents in photodynamic therapy (PDT). In the present study we have employed nanoemulsion-templated oil-core multilayer nanocapsules as robust nanocarriers for a cyanine-type photosensitizer IR-786.

Compact and linearly growing polyelectrolyte multilayer films have been used to suppress desorption of drugs, nanoparticles or proteins from underlying polyelectrolyte multilayer films as well as to significantly change their mechanical properties. The polyelectrolyte based capping layers are however cumbersome
Articles
We present an article that discusses two applications in particular; first, using these layers as polyelectrolyte membranes to control permeability.
