Electrochemical sensing provides a quantitative alternative to colorimetric reactions within paper-based devices. The paper-based devices were fabricated by screen printing the conductive and reference inks onto porous substrates that were evaluated using cyclic voltammetry. Devices were evaluated based on the magnitude of the average anodic peak height, which correlates with...
Diatoms are single celled eukaryotic microalgae that self-assemble complex SiO₂
nanostructures by sillafin proteins within their cell wall. There has been increasing
interest in mimicking the diatom’s silica self-assembly process for fabricating metal
oxide nanoparticles, namely germanium dioxide (GeO₂). GeO₂ has a higher refractive
index than silica, enabling it to...
Surface-associated thrombosis is a critical concern in medical device development. Current extracorporeal circulation units require systemic anticoagulation to avoid thrombosis, which can cause adverse effects such as thrombocytopenia, hypertriglyceridemia, and hyperkalemia. To address this issue, we combine the technology of polydopamine (PDA) functionalization with slippery liquid infused porous surfaces (SLIPS)....
Metamix is a mixture of botanical compounds that promote healing and prevent infection for burns and diabetic ulcers. In this thesis, metamix was incorporated into 1.75 weight percent gellan gum hydrogels as a drug delivery method for burned skin. The ideal concentration of metamix was 25% by solution volume for...
Electroanalytical techniques allow scientists and engineers to characterize bulk solutions as well as interfaces. Potentiostats are commonly used by researchers in a variety of disciplines to analyze the chemistry which occurs at a working electrode surface. Advancements in microelectronics and the proliferation of open-source designs have allowed researchers to construct...
Glioblastoma multiforme is the most common primary brain tumor in adults ages 45-70, with over 12,120 new cases in the U.S. predicted for 2016 alone. Glioblastoma is also one of the most difficult cancers to treat because the tumor cells tend to invade into the surrounding healthy tissue, making it...

Rapid and effective treatment of burn injuries is critical to prevent long term damage. Besides the pain associated with the burn injury due to damage and death of surrounding tissue and cells, there is a large risk for complications, particularly infection, following a burn injury. To address these risks, Meta...
Nowadays, woody biomass is becoming increasingly significant because of its renewability and biodegradability. Lots of opportunities have been found to use excessive biological resources to derive products as diverse as fuels, heat, electricity, chemicals, food, clothing, paper, and much more. As such, biomass plays an important role in meeting demands...
Essential oils have numerous chemical and therapeutic applications. Some oil extraction methods, including steam distillation, require a large energy input. An alternative technique with a lower energy demand is the extraction of oils using supercritical liquid carbon dioxide (CO2), which extracts essential oils with minimal environmental impact. While this often...
