A Highly Conductive, Flexible, And 3d-Printable Carbon Nanotube-Elastomer Ink For Additive Bio-Manufacturing, Andy Shar, Phillip Glass, Daeha Joung Ph.D.
A Highly Conductive, Flexible, And 3d-Printable Carbon Nanotube-Elastomer Ink For Additive Bio-Manufacturing, Andy Shar, Phillip Glass, Daeha Joung Ph.D.
Undergraduate Research Posters
The synthesis of a highly conductive, flexible, 3D-printable, and biocompatible ink has been of great interest in the field of bio-based additive manufacturing. Various applications include ultra-sensitive, microscale tactile sensors, patient-customizable scaffolds for cardiac and nerve tissue regeneration, and flexible electrocardiogram (ECG) electrodes. Here, a novel elastomeric carbon nanocomposite is presented consisting of amino-functionalized carbon nanotubes (CNT-NH2) homogenously dispersed in a one-part room-temperature vulcanizing (RTV) silicone matrix. The use of acetone as a swelling solvent aids in electrical percolation through the elastomer matrix. CNT-NH2 ratios can be tuned to fit various needs; higher tensile strength is favored …

Sensors And Wearables In Oncology: A Study Of The Barriers And Facilitators To Adoption, Sam Hanna
Doctor of Philosophy in Translational Health Sciences Dissertations
Innovation, although a subject of considerable debate (e.g., Baregheh et al., 2009; Christensen, 1997), can be defined as the introduction and dissemination of a new or a different idea into use or practice that drives impact (Solis and Sinfield, 2014). Many studies and editorials have highlighted the complexity of the United States health system and detailed the slow speed by which innovative ideas materialize into impactful innovations (Continuing America’s leadership (2017); England & Stewart (2007); Kannampallil, Schauer, Cohen & Patel (2011)). While there are many advances in sensor and wearable technologies in this instance, the adoption rate by oncologists has …
Towards An In Vitro Model Of Testing Osteoblast Cellular Function In Contact With Various Surfaces, Raheleh Miralami
Towards An In Vitro Model Of Testing Osteoblast Cellular Function In Contact With Various Surfaces, Raheleh Miralami
Theses & Dissertations
Past studies have shown that the success of total joint replacements depends on the biocompatibility of orthopaedic materials, which can be improved by modifying the implant surface. However, the exact roles of these modifications and their effective mechanisms are poorly understood. The objective of this study was to develop and evaluate a model system to investigate the impact of nano-structured surfaces, produced by the ion beam-assisted deposition (IBAD) technique, on biomarkers of osteointegration using an in vitro model. The IBAD technique was employed to deposit zirconium oxide (ZrO2), Titanium oxide (TiO2), and Titanium (Ti) nano-films on …
Calcium Phosphate As A Key Material For Socially Responsible Tissue Engineering, Vuk Uskoković, Victoria M. Wu
Calcium Phosphate As A Key Material For Socially Responsible Tissue Engineering, Vuk Uskoković, Victoria M. Wu
Pharmacy Faculty Articles and Research
Socially responsible technologies are designed while taking into consideration the socioeconomic, geopolitical and environmental limitations of regions in which they will be implemented. In the medical context, this involves making therapeutic platforms more accessible and affordable to patients in poor regions of the world wherein a given disease is endemic. This often necessitates going against the reigning trend of making therapeutic nanoparticles ever more structurally complex and expensive. However, studies aimed at simplifying materials and formulations while maintaining the functionality and therapeutic response of their more complex counterparts seldom provoke a significant interest in the scientific community. In this review …
In Vitro Analysis Of Nanoparticulate Hydroxyapatite/Chitosan Composites As Potential Drug Delivery Platforms For The Sustained Release Of Antibiotics In The Treatment Of Osteomyelitis, Vuk Uskoković, Tejal A. Dasai
In Vitro Analysis Of Nanoparticulate Hydroxyapatite/Chitosan Composites As Potential Drug Delivery Platforms For The Sustained Release Of Antibiotics In The Treatment Of Osteomyelitis, Vuk Uskoković, Tejal A. Dasai
Pharmacy Faculty Articles and Research
Nanoparticulate composites of hydroxyapatite (HAp) and chitosan were synthesized by ultrasound-assisted sequential precipitation and characterized for their microstructure at the atomic scale, surface charge, drug release properties, and combined antibacterial and osteogenic response. Crystallinity of HAp nanoparticles was reduced because of the interference of the surface layers of chitosan with the dissolution/reprecipitation-mediated recrystallization mechanism that conditions the transition from the as-precipitated amorphous calcium phosphate phase to the most thermodynamically stable one—HAp. Embedment of 5–10 nm sized, narrowly dispersed HAp nanoparticles within the polymeric matrix mitigated the burst release of the small molecule model drug, fluorescein, bound to HAp by physisorption, …
