  • Patent number: 11572477
    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.

  • Patent number: 10682313
    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.

  • Patent number: 8163851
    Abstract: The invention provides a polymeric salt, wherein the monomer unit of the polymeric salt comprises two nitrogen containing heterocyclic groups joined by a rigid linker group. The nitrogen atoms of the heterocyclic groups are disposed so as to enable a polymeric carbene formed by from the polymeric salt to complex with a metal atom. The invention also provides a polymeric metal complex which may be made from the polymeric salt, and which may be used in a Suzuki coupling reaction. The polymeric salt may be used as a heterogeneous organic catalyst for cyanation reaction.
