Abstract Bacterial infections associated with metal implants are severe problems affecting a considerable amount of people with dental or orthopedic implants. This study aims to examine the antibacterial effect of a Titanium-peroxy gel layer on the modified surface of commercially pure titanium grade 2. Variations in a multi-step surface modification procedure were tested to determine the best combination that provided an antibacterial effect while enhancing bioactivity without compromising bioc...

Abstract An inflammatory reaction occurs following biomaterial implantation in the body, which produce toxic byproducts such as reactive oxygen species (ROS). Although ROS is required to clear the wound, excessive ROS can damage the tissue around the implant site, eventually leading to implant failure. One approach to control the inflammatory response is to incorporate an antioxidant into the biomaterial in order to scavenge ROS produced by activated phagocytes. In the present study, an organose...

Nanomaterials offer an advantage over traditional biomaterials since cells naturally communicate via nanoscale interactions. The extracellular matrix, for example, modulates adhesion and cellular functions via nanoscale features. Thus incorporating nanofeatures into biomaterials may promote tissue regeneration, however in certain forms and doses nanomaterials can also cause harm. A thorough understanding of cell-nanomaterial interactions is therefore necessary to better design functional biomate...

Hydroxyapatite with different aspect ratios such as nano dots, sheets, rods and fibers were synthesized by the hydrothermal and precipitation methods respectively. It is not difficult to synthesize nanohydroxyapatite (nHA) with a low aspect ratio using published methods. However, it is still a challenge to synthesize nHA particles with a high aspect ratio, such as nHA fibers, using a well-controlled and repeatable method. In this study, we describe a method to control the aspect ratio of nHA by ...
