Shelf Life Study Of Electrospun Plga Copolymers, Sean Youra, Nick Hudson
Biomedical Engineering
Poly(lactic-co-glycolic acid) (PLGA) is one of the most commonly used copolymers for electrospinning in tissue engineering applications. However, most research has not focused on the copolymer itself in regards to how long it can be used effectively and if varying the concentrations of polylactic acid (PLA) and polyglycolic acid (PGA) affect the resulting properties. Electrospinning is the method we use to create the three-dimensional constructs, or “scaffolds”, for the blood vessel mimic (BVM) in the tissue engineering lab. The aim of our project was to investigate if the morphology and mechanical properties of the scaffolds changed over time when they …

Biofilms are present in virtually every solid-liquid contact surface and are partially responsible for some diseases and water cleaning. They are a community of a variety of organisms that live symbiotically and are bound together by extracellular polymeric substances, or EPS. Biofilms go through five stages of development. These include initial and irreversible attachments, maturations I and II, and dispersion. In the dental world, biofilms are often associated with mouth infections including dental caries, gingivitis and periodontitis. Elderly denture wearers are susceptible to the pathogen-causing bacteria associated with these diseases, particularly those who have Alzheimer's disease or other forms of …
