Abstract: Techniques regarding ionene compositions with antimicrobial functionality are provided. For example, one or more embodiments can comprise a monomer, which can comprise a single ionene unit. The single ionene unit can comprise a cation distributed along a molecular backbone. Also, a hydrophobic functional group can be covalently bonded to the molecular backbone, and the single ionene unit can have antimicrobial functionality.

Abstract: Disclosed is a block copolymer(BCP) capable of self-assembly into nanoparticles for the delivery of hydrophobic cargos. The BCP includes a hydrophobic block that contains a thioether functional group that is susceptible to oxidation, transforming the solubility of the block from hydrophobic to hydrophilic, thereby releasing the hydrophobic cargo of the nanoparticle.

Abstract: Antibacterial coatings and methods of making the antibacterial coatings are described herein. In particular, a method for forming an organocatalyzed polythioether coating is provided in which a first solution including a bis-silylated dithiol and a fluoroarene is prepared. A second solution including an organocatalyst is prepared. The first solution and the second solution are mixed to form a mixed solution. The mixed solution is applied to a substrate, and the substrate is cured.

Abstract: The subject matter of this invention relates to block copolymers (BCPs) and, more particularly, to block copolymers capable of self-assembly into nanoparticles for the delivery of hydrophobic cargos. The BCPs include a hydrophobic block that contains a thioether functional group that is susceptible to oxidation, transforming the solubility of the block from hydrophobic to hydrophilic, thereby releasing the hydrophobic cargo of the nanoparticle.

Abstract: Antibacterial coatings and methods of making the antibacterial coatings are described herein. A first branched polyethylenimine (BPEI) layer is formed and a first glyoxal layer is formed on a surface of the BPEI layer. The first BPEI layer and the first glyoxal layer are cured to form a crosslinked BPEI coating. The first BPEI layer can be modified with superhydrophobic moieties, superhydrophilic moieties, or negatively charged moieties to increase the antifouling characteristics of the coating. The first BPEI layer can be modified with contact-killing bactericidal moieties to increase the bactericidal characteristics of the coating.
