| Abstract Scope |
One of the biggest challenges to develop nanoparticle modified biomedical implant material is to stably attach these metallic nanoparticles on different surfaces especially polymer surfaces.We have addressed this important issue by developing a new plasma-enabled process viz. Plasma Electroless Reduction (PER) to form/deposit gold and silver nanostructures on different polymer material surfaces (2D and 3D) such as polypropylene based facemasks and 3D printed scaffolds. It is well known that there are toxicity issues offered by the rapid release of the metallic nanoparticles from the implants into the blood stream. This issue could be only addressed by ensuring the stable anchoring of the metallic nanostructures on implant surface. In the current PER process, we were able to stably anchor gold and silver nanoparticles on the surface of 3D printed Polymers without any rapid release into the surroundings. In vitro anti-bacterial and cells studies will also be presented. |
