Abstract: Surgical adhesives that include a blend of two different thermoreversible gelling polymers and a crosslinking agent are described. The first thermoreversible gelling polymer is partially or fully acrylated and the second thermoreversible gelling polymer includes dual functionality including acrylate functionality and amine-reactive functionality. The adhesives can provide gelling and covalent crosslinking within the polymers of the adhesive as well as crosslinking with surrounding tissue.

Abstract: A system of stabilized metallic nanoparticles is described that includes metallic nanoparticles coated with a hydrophilic polymer that has been reacted with a catechol-based ligand. Also described are stable, metallic nanoparticles that can be used alone or in conjunction with biocides, antibiotics, or other treatment systems in a method to disrupt a biofilm and facilitate its removal from a surface. The nanoparticles can be metal, such as platinum, silver, iron (II, III) oxide (Fe3O4), and gold. The nanoparticles can be sterically stabilized, such as with a polymer, or charge stabilized, such as with citrate, resulting in nanoparticles having modified surfaces. This surface modification is thought to enhance the stability of the nanoparticles and decrease their likelihood of aggregation, which, in turn, enhances their ability to disrupt and disperse existing biofilms.
