Injectable hydrogels are important for use in tissue engineering due to their permeability and biocompatibility. Those that have shear thinning properties allow for minimally-invasive surgical procedures and a way to administer bioactive agents, and therapeutic cells by injection. Currently available injectable hydrogels have a single or dual input/stimulus for crosslinking which limits the range of mechanical properties and often utilize potentially toxic ultraviolet radiation that reduces viability of injected cells. To overcome these shortcomings, a tri-stimuli-responsive alginate-based injectable hydrogel was developed based on: 1) supramolecular complex formation between β-cyclodextrin (β-CD) conjugated alginate and thermo-responsive tri-block Pluronic® copolymers, 2) visible light …

Pneumothorax, or a collapsed lung, is a serious medical condition resulting when air or fluid escapes the lung into the chest cavity and prevents the lung from inflating. Few viable means of sealing the damaged and leaking tissues are currently available, leading to longer hospital stays, multiple interventions, and increasing costs of care. The motivation of this dissertation is to engineer a novel polysaccharide-based therapeutic surgical sealant, which can be utilized to seal trauma-induced damage to the outer lining of the lung, i.e. pleura, preventing or reversing lung collapse to restore normal breathing function.
The use of polysaccharides, such as …
