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 …
Finite Element Analysis Of The Application Of Ultrasound-Generated Acoustic Radiation Force To Biomaterials, Nicole J. Piscopo
Finite Element Analysis Of The Application Of Ultrasound-Generated Acoustic Radiation Force To Biomaterials, Nicole J. Piscopo

While most bone fractures can heal simply by being stabilized, others can take a longer time to rejoin or they could fail to merge back together completely. Numerous studies have shown the positive effects that ultrasonic therapy have had on delayed-union and non-union bone fracture repair but little is known as to what specific biological mechanisms are at play. Ultrasound may be a valuable tool for bone tissue regeneration at these fracture sites using a tissue engineering approach, however, more must be understood about its impact on stimulating tissues to heal before this can be a reality. For that reason, …
Design Of A Simple Device For Accurate Measurement Of Human Blood Viscosity In Oxygenated And Deoxygenated Conditions, Catherine E. Oliver, Jessica Hockla, Divya Kamireddi
Design Of A Simple Device For Accurate Measurement Of Human Blood Viscosity In Oxygenated And Deoxygenated Conditions, Catherine E. Oliver, Jessica Hockla, Divya Kamireddi
Honors Scholar Theses
The purpose of this research is to design, fabricate, and test a simple device that can accurately measure the viscosity of whole blood in both an oxygenated and a deoxygenated environment. The ideal device is easy to operate, inexpensive to fabricate, and is usable outside of a laboratory setting. The microfluidic rheometer presented here was fabricated using a wet chemical etching method. Using the channel dimensions, the known viscosity of a reference fluid, and the velocity of fluid flow of the sample and a reference fluid through the microchannels the unknown viscosity of a sample fluid is calculated.
