Description of Publication: Cellulose nanofibrils is one of the future potential giants in the medical implant industry. Its unique properties make it the ideal material for use in both permanent prosthetic devices and non- permanent implants such as screws and plates. To increase the usability of this material, the addition of super paramagnetic iron oxide nanoparticles is needed to gain MRI and X-Ray visibility. The methodology for how to homogenously integrate these particles into the system using the addition of coating agents is explored. This research demonstrates that the addition of coating agents to the iron oxide nanoparticles can affect both the pH flocculation behavior and the adhesion of the particles to fibrils. In addition, the research finds that the addition of coating agents affects the physical characteristics of the fibrils themselves.
