The design and manufacture of novel materials has served as the bedrock for tissue engineering and regenerative medicine. There exists a need for more biocompatible implantable materials in the biomedical device space. The approach to developing biomaterials fit for biomedical devices has been focused on decreasing overall physiological interaction with the local environment. However, the development of more biomechanically favorable materials has placed an emphasis on designing materials that display biomimetic and biomechanical properties resembling that of the host tissue at the implant site. As biomaterials engineering has progressed, the race to find materials that interact at the nano- and …

A great need exists for innovative, functional materials. Specifically, functional materials must meet the necessary mechanical and interfacial properties for successful bio-integration for end goals such as medical implants. A gap in the knowledge existed before this work. This work addressed that gap through an experimental approach that employed low-temperature plasma (LTP) processing of fibrous, polyester constructs to produce functional materials. First, atmospheric-pressure plasma processing of electrospun polyester fibers, in a tubular geometry, was reported. Characterization of that system was conducted. Next, the effects of magnetized plasmas were reported. That report was a novel application of magnetized plasma and showed …

Producing tissue engineering scaffolds which mimic the structure and mechanical properties of the native extracellular matrix (ECM) is an important challenge in developing synthetic tissue replacements. Electrospinning is a frequently used technique to fabricate 3D nanofibrous scaffolds which match the dimensions of the fibrous elements of ECM. However, the mechanical behavior of electrospun materials is complex and challenging to predict. To aid in understanding the mechanical properties of electrospun materials, a microtensile testing platform was developed. This platform was used to quantify the mechanical properties of arrays of individual electrospun nanofibers. Additionally, this device permitted optical strain recording to visualize …

Synthetic calcium phosphates (CAP) such as hydroxyapatite (HA) have been used as regenerative bone graft materials and also as thin films to improve the integration of biomedical implant devices within skeletal tissue. Pulsed laser deposition (PLD) can deposit crystalline HA with significant adhesion on titanium biomaterials. However, there are PLD processing constraints due to the complex physical and chemical interactions occurring simultaneously during PLD, which influence ablation plume formation and development. In this investigation PLD CAP films were engineered with a focus on novel decoupling of partial pressure of H2O (g) (P(H2O)) from total background pressure, in combination with substrate …
