Evaluating The Effects Of Antibody-Conjugated Multi-Walled Carbon Nanotubes In Combination With Microwave Irradiation, Amy Chall Jan 2019

Evaluating The Effects Of Antibody-Conjugated Multi-Walled Carbon Nanotubes In Combination With Microwave Irradiation, Amy Chall

College of Graduate Studies: Theses & Dissertations

Cancer remains one of the largest public health concerns of our day, particularly in developed countries where technological advances have allowed populations to live well into their eighth decade. In America, those in their 80’s have a 1 in 2 chance of developing cancer in their lifetime. Prostate cancer, specifically is the second leading cause of cancer deaths in males. Traditional cancer therapies cause high levels of toxicity to the patient due to mechanisms of action that often attack cancer cells and healthy cells alike. The holy grail of cancer research is to find a treatment that targets the cancer …

Combination Strategies For Targeted Delivery Of Nanoparticles For Cancer Therapy, Zhonglie He, Kangze Liu, Hugh Byrne, Patrick J. Cullen, Furong Tian, James Curtin Jan 2019

Combination Strategies For Targeted Delivery Of Nanoparticles For Cancer Therapy, Zhonglie He, Kangze Liu, Hugh Byrne, Patrick J. Cullen, Furong Tian, James Curtin

Books / book chapters

Pharmaceuticals, and more recently biopharmaceuticals, have become the mainstay for antineoplastic treatments in combination with surgical interventions and radiation therapy. In recent years, advances have been made in the development of nano-technological interventions for the treatment of cancer alone or in combination with existing therapeutic modalities. Nanotechnology used for therapeutic drug delivery and sensitization of photodynamic, sonodynamic and radiotherapy are now being tested in preclinical and clinical trials for the treatment of cancer. This article will review the current state of the art for nanotechnology therapies with an emphasis on targeted drug delivery and the observed and likely benefits when …

Fabrication And Characterization Of Nanofiber Nylon-6-Mwcnt As An Electrochemical Sensor For Sodium Ions Concentration Detection In Sweat, Kelsey Mills Jan 2019

Fabrication And Characterization Of Nanofiber Nylon-6-Mwcnt As An Electrochemical Sensor For Sodium Ions Concentration Detection In Sweat, Kelsey Mills

Williams Honors College, Honors Research Projects

Fabrication and characterization nylon-6-MWCNT nanofiber as an electrochemical sensor to detect sodium ion concentrations specifically in sweat. Using contact angle to determine surface morphology and chronoamperometry testing to identify ideal sensor conditions, tests optimized parameters like weight percent of nylon or other polymers, carbon nanotube (CNT) isomer, and solution concentration to determine reproducibility of functional sensors. Utilizing the electric qualities of carbon nanotubes partnered with the sodium ion selectivity of calixarene treatment and polymers unique properties like flexibility and scalability create open an arena for optimizing sodium ion sensors for further development for functional prototypes. Morphology tests showed that the …

Multigenerational Genomic And Epigenetic Effects Of Manufactured Silver Nanomaterials In Caenorhabditis Elegans, Anye Wamucho Jan 2019

Multigenerational Genomic And Epigenetic Effects Of Manufactured Silver Nanomaterials In Caenorhabditis Elegans, Anye Wamucho

Theses and Dissertations--Toxicology and Cancer Biology

There has been an increase in the incorporation of silver nanomaterials into consumer products due to their antimicrobial properties. Therefore there is potential for silver nanoparticles (Ag-NPs) to leach out into the environment during different life-cycle stages of these nanomaterial-containing products. Concern about the toxicity of Ag-NPs has led to investigations into their toxic effects on a variety of organisms mainly using acute and sub-chronic, single-generation exposures. The focus of this project was to understand the effects of long-term continuous multigenerational exposure to AgNO3 and Ag-NPs in both pristine and environmentally transformed forms, on the model organism, Caenorhabditis elegans …

The biological interactions of graphene have been extensively investigated over the last 10 years. However, very little is known about graphene interactions with the cell surface and how the graphene internalization process is driven and mediated by specific recognition sites at the interface with the cell. In this work, we propose a methodology to investigate direct molecular correlations between the biomolecular corona of graphene and specific cell receptors, showing that key protein recognition motifs, presented on the nanomaterial surface, can engage selectively with specific cell receptors. We consider the case of apolipoprotein A-I, found to be very abundant in the …
