Central nervous system neural device functionality hinges on effective communication with surrounding neurons. This depends on both the permissiveness of the device material to promote neuron integration and the ability of the device to avoid a chronic inflammatory response. Here, a facile approach has been developed exploring the multiple functionalities of hydrogel particles to provide cues to impart neural integration for such materials. Three distinct, yet interconnected tasks were undertaken: investigating hydrogel particle-modified substrate neuron integration and central nervous system inflammatory response, investigating guided hydrogel particle adsorption, and investigating hydrogel particles as local reservoirs for counteracting adverse effects from oxidative …

In 2012, approximately 6.8 million people in the United States were diagnosed with orthopedic injuries or diseases. Over 500,000 people in the United States underwent bone grafting procedures, which cost 2.5 billion dollars per year and can result in complications. Polymer-based grafting scaffolds can facilitate 3D bone tissue growth in a localized, sustained manner. However, bone regeneration requires the orchestration of a sequence of events. Current scaffolds based on degradation and diffusion cannot provide sequential deliveries. We aimed to design a polymer scaffold that can release one payload diffusively at early time points, followed by ultrasonically triggered release of a …

Honors Scholar Theses
The field of tissue engineering focuses on delivering patient-derived stem cells to the body through the use of degradable biomaterials, such as hydrogels, which are infused into engineered scaffolds. Hydrogels act as templates to support and guide cells towards the regeneration of new tissue. In this study, we introduce a completely intraoperative procedure for obtaining a fibrin hydrogel for tissue engineering applications. In the past, fibrin hydrogel has been commonly formed by combining fibrinogen protein with animal-derived thrombin. Instead, we have developed an automated, and therefore reproducible, protocol to isolate and form fibrin hydrogel without the use of animal-derived thrombin. …
