Antimicrobial compositions and methods for depositing or coating the antimicrobial or antibacterial compositions on a substrate to prevent microbial adhesion are provided. The antimicrobial composition may include a cationic polymer having a poly-allylamine backbone. A portion of the poly-allylamine backbone may be functionalized with at least one of a guanidine functional group and a biguanide functional group.

Oral care compositions and methods for anti-attachment polymers and coatings

The invention provides compositions comprising a plurality of polymer layers for preventing or inhibiting microbial infections. Specifically, the invention provides a combination of a cationic polymer layer that resists adhesion of a microbe to its surface and an anionic polymer layer that releases a cationic anti-microbial agent in response to a change in pH or electrostatic balance.

Antimicrobial polymer layers

The invention relates to a multifunctional chitosan grafted surface. Specifically, the invention relates to a chitosan modified with a quaternary ammonium salt (CH-Q) grafted surface that provides various functional properties, including stability (pH 3-9) and unique pH dependent swelling and antibacterial properties.
