System and method for fabricating nanoparticle filler material dispersions and producing improved compounds containing hydrophobic plastic polymers
A system and method of forming a plastic blend that includes nanoparticles of filler material evenly dispersed, without agglomeration of particles, throughout a hydrophobic polymer. A slurry is created that contains water and nanoparticles of a filler material. The filler materials are selected from a group consisting of crystalline cellulose, cellulose fiber, chitosan and chitin. A dispersion aid is provided that has a melting point in a temperature range. The slurry is heated and mixed to a temperature that is above the melt point range of the dispersion aid. The dispersion aid is added. The slurry is cooled to a temperature that is below the melting point of the dispersion aid. This causes the dispersion aid to solidify and entrap the nanoparticles within solid compound. The solid compound is dried and then reduced into a powder. The powder is the fill composition that is melt compounded for use.

Layer by layer coated mesh for local release of bio-active proteins
The present invention relates to biomaterials coated with an active agent eluting coating, wherein implantation of the coated biomaterial results in reduced implant-related complications and/or improved integration of the biomaterial into the host tissue and further relates to kits containing the coated biomaterial. The present invention also relates to methods and kits for coating the biomaterial. It is based, at least in part, on the discovery that biomaterial coated with a cytokine eluting coating resulted in the shift of early stage macrophage polarization that were associated with positive long-term effects such as minimized capsule formation and improved tissue quality and composition as compared to uncoated biomaterials.
