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.
