Abstract: A bioactive adhesive for use in securing soft tissue to osseointegrated percutaneous devices includes a hydrogel precursor and a multiplicity of metal-containing mesoporous silicate nanoparticles dispersed throughout the hydrogel precursor. An antimicrobial peptide is adsorbed on surfaces of the mesoporous silicate nanoparticles, incorporated in the mesoporous silicate nanoparticles, or both. The metal-containing mesoporous silicate nanoparticles can include calcium, strontium or both and are configured to release the antimicrobial peptide over time. Adhering tissue to a metal surface includes disposing the bioactive adhesive on a metal surface, contacting a portion of tissue with the adhesive composition, and curing the adhesive composition, thereby adhering the portion of tissue to the metal surface.

Abstract: An ultraviolet photopolymerizable composition for soft tissue attachment includes trimethylolpropane tris(3-mercaptopropionate) (TMTMP), a photoinitiator, a solvent, and one or more of trimethylolpropane trimethacrylate (TMPTMA), pentaerythritol triacrylate (PETA), dopamine methacrylamide (DMA), and n-phenethylmethacrylamide (PEMAD). Coating a substrate with a polymeric coating includes contacting a substrate with the ultraviolet photopolymerizable and irradiating the composition with ultraviolet radiation to yield a polymeric coating on the substrate. Treating a substrate includes contacting the substrate with the composition and irradiating the composition with ultraviolet radiation to yield a polymeric coating on the substrate.

Abstract: An example article may include a dental surface, a hydrophobic coating on the dental surface, and a restorative layer on the hydrophobic coating. An example technique may include applying, on a dental surface, a hydrophobic coating comprising an amphiphilic agent. The hydrophobic coating may provide a water contact angle of greater than or equal to about 50° on the dental surface. The example technique may include applying a restorative layer to the hydrophobic coating. An example kit may include a dental restorative composition and a hydrophobic coating composition. The hydrophobic coating composition may include an amphiphilic agent. The hydrophobic coating composition may be configured to provide a water contact angle of greater than or equal to about 50° on a dental surface.

Abstract: The invention provides antibiotic BPI Fold Containing Family A Member 2 (BPIFA2) peptides, compositions comprising a BPIFA2 peptide, hydrogels comprising a BPIFA2 peptide, nanofibrillar networks comprising a BPIFA2 peptide, and tissue scaffolds comprising BPIFA2 peptides.

Abstract: In some examples, the disclosure relates to a method including applying biomimetic mineralization process to an enamel defect of a tooth, wherein the applied biomimetic mineralization process remineralizes the tooth in the enamel defect. For example, applying a biomimetic mineralization process may include applying a polymer stabilized biomimetic mineralization composition in the area of the enamel defect and matrices, wherein the biomimetic mineralization composition infiltrates into a porosity of the enamel defect and crystalizes to remineralize the enamel defect. An example polymer stabilized biomimetic mineralization composition includes calcium, phosphate, and a polyanionic additive.
