Ultrasonically Responsive Tissue Engineering Scaffolds For The Temporal Control Over Osteo-Inductive Growth Factor Delivery, Catherine Linh
Ultrasonically Responsive Tissue Engineering Scaffolds For The Temporal Control Over Osteo-Inductive Growth Factor Delivery, Catherine Linh
Senior Honors Projects
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 …
