Engineering Advanced Micro And Nanofiber Materials For Biomedical Applications, Alec D. Mccarthy

Theses & Dissertations

At the functional crossroads of engineering and biomedical sciences lies the interdisciplinary field of biomedical engineering. Principles of biomedical engineering are vast, and the rigorous application of engineering towards clinically-relevant medicine has the ability to take novel concepts from bench to bedside. Arguably one of the most promising and productive sub-fields within the biomedical engineering discipline is biomaterial engineering. Here, novel biomaterials, synthesized from natural, synthetic, or hybrid materials, can be used in tissue repair and regeneration, hemostasis, as anatomical support and drug delivery vessels, or as diagnostic devices.

Of particular interest are applications of nanofiber and microfiber objects, which …

Design And Development Of Two Component Hydrogel Ejector For Three-Dimensional Cell Growth, Thomas Dunkle, Jessica Deschamps, Connie Dam

Honors Scholar Theses

Hydrogels are useful in wound healing, drug delivery, and tissue engineering applications, but the available methods of injecting them quickly and noninvasively are limited. The medical industry does not yet have access to an all-purpose device that can quickly synthesize hydrogels of different shapes and sizes. Many synthesis procedures that have been developed result in the formation of amorphous hydrogels. While generally useful, amorphous hydrogels exhibit limited capability in tissue engineering applications, especially due to their viscous properties. This endeavor aims to modulate the appropriate gelation parameters, optimize the injection process, and create a prototype that allows for the extrusion …

Trabecular Calcium Phosphate Scaffolds For Bone Regeneration, Mark Ryan Appleford

Theses and Dissertations (ETD)

Bone tissue engineering represents a strategy for the repair or regeneration of damaged bone in the body. The science underlying this clinical therapy bridges the traditional fields of cell biology, materials science and mechanical engineering with the aim to identify how cells behave on physiologically relevant materials with natural mechanical stimuli. The objectives of this research were to develop and characterize calcium phosphate ceramic scaffolds matched to the local architecture of natural trabecular bone and to apply tissue engineering strategies for the study of cell behavior in both in vitro and in vivo models.The specific role of environment on cell …
