Internet Of Things For Sustainable Human Health, Abdul Salam Jan 2020

Internet Of Things For Sustainable Human Health, Abdul Salam

Faculty Publications

The sustainable health IoT has the strong potential to bring tremendous improvements in human health and well-being through sensing, and monitoring of health impacts across the whole spectrum of climate change. The sustainable health IoT enables development of a systems approach in the area of human health and ecosystem. It allows integration of broader health sub-areas in a bigger archetype for improving sustainability in health in the realm of social, economic, and environmental sectors. This integration provides a powerful health IoT framework for sustainable health and community goals in the wake of changing climate. In this chapter, a detailed description …


Enhancing Chemosensitivity Of Lung Cancers By Manipulating The Tumor Microenvironment: Local Lung Delivery And Nanocarrier-Based Therapies, Hanming Zhang Jan 2020

Enhancing Chemosensitivity Of Lung Cancers By Manipulating The Tumor Microenvironment: Local Lung Delivery And Nanocarrier-Based Therapies, Hanming Zhang

Theses and Dissertations

Cancer is the second leading cause of death in United States causing an estimated six hundred thousand death in 2019. Among different types of cancer, lung cancer is the leading cause of cancer related death in both male and female. While targeted therapy and immunotherapy have shown promising clinical outcomes, currently there remain a significant proportion of patients who do not benefit from these strategies or who cannot tolerate them, making Pt based doublet chemotherapy still an indispensable component in almost all stages of treatment. However, partially due to the poor tumor distribution of small molecule drug, the development of …


Growth Optimization Of Zinc-Oxide Nanowires/Nanorods Using Hydrothermal Synthesis On Silicon Wafers, Mythili Ananthula Jan 2020

Growth Optimization Of Zinc-Oxide Nanowires/Nanorods Using Hydrothermal Synthesis On Silicon Wafers, Mythili Ananthula

Graduate Research Theses & Dissertations

This research paper aims to grow and optically characterize the Zinc-Oxide (ZnO) nanowires grown using the hydrothermal synthesis method on different semiconductor wafers. We have developed the samples on p-type silicon, n-type silicon, and silicon di-oxide wafers at different temperatures, molarities, and times. Using hydrothermal synthesis method Zinc Oxide nanowires are grown. Zinc Nitrate Hexa-hydrate and Hexamethylenetetramine are chemical components used in the hydrothermal synthesis method at low temperatures.

Different types of analysis have been done on these samples with the help of “Argonne National Laboratory.” The optical absorption spectra were obtained using Perkin Elmer LAMBDA 950 UV-VIS-NIR Spectrophotometer. Photoluminescence …


Shape Tuning Of Silicon Nano-Tip Arrays Through Reactive Ion Etching For Cold Field Emission, Giridhar Tulasi Ram Sankabathula Jan 2020

Shape Tuning Of Silicon Nano-Tip Arrays Through Reactive Ion Etching For Cold Field Emission, Giridhar Tulasi Ram Sankabathula

Graduate Research Theses & Dissertations

Large area silicon nano-tip arrays have been predominantly used as cold cathode electron sources in the wide range of field emission applications. Various fabrication methodologies have been developed over the decades to obtain sharp-pointed field emitters. In this thesis, we mainly emphasized on reproducing high aspect ratio field emitters and to study their surface topographical changes encountered through reactive ion etching. A discrete set of high-density field emitters have been fabricated over the large area surfaces through a three-step nanofabrication process. The surface curvatures of the obtained emitter tips are finely tuned with multiple oxidation cycles to achieve a tip’s …

Casein, β-lactoglobulin and α-lactalbumin are major milk protein allergens. In the present study, the structural modifications and antigenic response of these bovine milk allergens as induced by non-thermal treatment by atmospheric cold plasma were investigated. Spark discharge (SD) and glow discharge (GD), as previously characterized cold plasma systems, were used for protein treatments. Casein, β-lactoglobulin and α-lactalbumin were analyzed before and after plasma treatment using SDS-PAGE, FTIR, UPLC-MS/MS and ELISA. SDS-PAGE results revealed a reduction in the casein and α-lactalbumin intensity bands after SD or GD treatments; however, the β-lactoglobulin intensity band remained unchanged. FTIR studies revealed alterations in protein …


Formulation And Validation Of Nanoparticle Controlled Delivery For Chemotherapeutic Drug Products, Shani L. Levit Jan 2020

Formulation And Validation Of Nanoparticle Controlled Delivery For Chemotherapeutic Drug Products, Shani L. Levit

Theses and Dissertations

Taxol, a formulation of paclitaxel (PTX), is one of the most widely used anticancer drugs, particularly for treating recurring ovarian carcinomas following surgery. Clinically, PTX is used in combination with other drugs such as lapatinib (LAP) to increase treatment efficacy. Delivering drug combinations with nanoparticles has the potential to improve chemotherapy outcomes. In this study, we use Flash NanoPrecipitation, a rapid, scalable process to encapsulate weakly hydrophobic drugs (logP in vitro. Encapsulating either PTX or LAP into nanoparticles increases drug potency. When PTX and LAP are co-loaded in the same nanoparticle, they have a synergistic effect that is greater than …


Development Of Dexamethsone Sodium Phosphate Loaded Nanoparticles For Treating Corneal Allograft Rejection, Vineet R. Kulkarni Jan 2020

Development Of Dexamethsone Sodium Phosphate Loaded Nanoparticles For Treating Corneal Allograft Rejection, Vineet R. Kulkarni

Theses and Dissertations

Corneas are the most commonly transplanted tissue worldwide, with approximately 80,000 transplantations performed in the United States in 2018 alone. Corneal transplantation is used to restore the vision due to opaque corneas in various diseases such as fungal keratitis, keratoconus, Fuchs’s dystrophy, corneal ulceration, traumatic injury, abrasions or scarring, inflammation, and infection. Corneal transplant surgery could involve replacing the entire cornea (penetrating keratoplasty) or selective replacement of the corneal layers (e.g. Descemet’s membrane endothelial keratoplasty and deep anterior lamellar keratoplasty). Immunologic graft rejection is one of the main causes of graft failure in these corneal transplantations. The 2-year rejection rate …


Exosomes As Systemic Mediators Of Nanotube Induced Neurotoxicity, Christopher G. Canal Jan 2020

Exosomes As Systemic Mediators Of Nanotube Induced Neurotoxicity, Christopher G. Canal

Theses and Dissertations

Extra-pulmonary effects of nanoparticle inhalation have been well documented; however, mechanisms for conveying peripheral bioactivity remain elusive. Recent studies point to indirect molecular mediators shed into the circulation. Protein and lipid alternatives to cytokines or chemokines have been proposed, yet the diversity among responses suggests a broader assemblage of factors. Recently we have proposed proteolytic fragment peptides as an additional source of bioactivity, which interestingly were significantly associated with exosomal proteins after enrichment analysis. Here we tested whether modeled exposure to multi-walled carbon nanotubes (MWCNT) could alter the composition and bioactivity of circulating exosomes. Male C57BL/6 mice were exposed by …
