Survey Of The Performance Of 5 Nm Gold Nanoparticles Within An Ssdna-Stabilized Biosensor For The Detection Of Hg2+, Madalyn Zagajowski
Survey Of The Performance Of 5 Nm Gold Nanoparticles Within An Ssdna-Stabilized Biosensor For The Detection Of Hg2+, Madalyn Zagajowski
Scholar Week 2016 - present
The formation of a fluorescent biosensor complex consisting of 5 nm diameter gold nanoparticles (AuNPs) and single-stranded DNA (ssDNA) was conducted using a low-cost, efficient binding method. Furthermore, we assessed the analytical potential for the complex to detect mercury ions (Hg2+) in an aqueous solution upon collection of UV-vis and fluorescence spectrometry data for the AuNP-ssDNA complex. We aimed to investigate this potential due to the possibility that the nanoparticles formed utilizing this method would produce nanoparticles of too small a size to result in detectable fluorescence, thus the complex synthesized from this specific method was qualitatively evaluated …

Quantification Of Vitamin B12 In Two Cricket Species, Haley Smeltz
Quantification Of Vitamin B12 In Two Cricket Species, Haley Smeltz
Student Scholar Showcase
Entomophagy, or the eating of insects, has been practiced in the eastern world for centuries, however it is currently overlooked in the western nations. Studies have shown that insects, such as crickets, contain high levels of protein and minerals, however vitamin content is rarely studied. This study aims to quantify the vitamin B12 content in two cricket species, the common house cricket (Acheta domesticus) and the banded cricket (Gryllodes sigillatus). The vitamin B12 content of both cricket species will be quantified using reverse-phase high performance liquid chromatography (RP-HPLC). Prior to RP-HPLC analysis, all the …
Characterization Of Dimerization Domains On The Mannose-6-Phosphate/Insulin-Like Growth Factor 2 Receptor, Tyler Degener
Characterization Of Dimerization Domains On The Mannose-6-Phosphate/Insulin-Like Growth Factor 2 Receptor, Tyler Degener
UNO Student Research and Creative Activity Fair
The mannose-6-phosphate/insulin-like growth factor 2 (M6P/IGF2) receptor is a transmembrane protein with the ability to sequester growth factors from the extracellular matrix. This behavior links the receptor to tumor suppression. On a structural level, the extracellular portion of the protein is segmented into 15 homologous repeats, which can be divided further into 5 triplet domains, labelled 1-3, 4-6, 7-9, 10-12, and 13-15. Each triplet receptor displays its own unique ligand binding affinity, including the ability to form dimers with triplets on a second M6P/IGF2 receptor. In fact, previous studies indicate that this protein functions optimally when dimerized. Thus, the purpose …
Elemental Analysis Of Beer Manufactured In Virginia Satellite Breweries, Jennifer Wiliams
Elemental Analysis Of Beer Manufactured In Virginia Satellite Breweries, Jennifer Wiliams
Student Scholar Showcase
Financial incentives from the state and wider distribution potential have lured many west coast brewers to open satellite breweries in Virginia. Quality control is crucial for any brewery and especially important in satellite breweries that need to imitate the standard set by the parent brewery. Zinc, magnesium, iron, sodium manganese, and calcium are trace elements found in wort and are essential for enzymes that catalyze fermentation reactions. These elements protect against cell stress, play a crucial role in flocculation, and can affect the flavoring and coloration of beer. Barley, water, and hops are the sources of these elements in beer. …
Iso-Α-Acids Degradation In Beer, Emily Whittle
Iso-Α-Acids Degradation In Beer, Emily Whittle
Student Scholar Showcase
Iso-a-acids are one of the key components that provide bitterness to beer. Understanding the stability of beer flavor over extended period is useful to the rapidly expanding craft beer industry and to the consumer. The lupulin glands of hops (Humulus Lupulus, L.) contain three a-acids: humulone, adhumulone, and cohumulone. The a-acids are converted to six iso-a-acids upon boiling, this is the main reason for boiling wort during the brewing process. The six iso-a-acids are cis-isohumulone, trans-isohumulone, cis-isoadhumulone, trans-isoadhumulone, cis-isocohumulone, and trans-isocohumulone. We propose that the concentration of iso-a-acids in beer will decline over time …
Characterization Of The Mannose-6-Phosphate/Insulin-Like Growth Factor Ii Receptor Using 1-3mh, Zechariah Craig
Characterization Of The Mannose-6-Phosphate/Insulin-Like Growth Factor Ii Receptor Using 1-3mh, Zechariah Craig
UNO Student Research and Creative Activity Fair
The mannose-6-phosphate/insulin-like growth factor 2 receptor (M6P/IGF2R), a recombinant triplet protein receptor for studies involving receptor dimerization, plays a pivotal role in mediating cellular growth. This receptor is comprised of fifteen similar units that fold into five triplet subunits. The goal of this experiment is to investigate how to make the 1-3MH protein more stable at the DNA level and generate a larger yield from DNA extractions for more effective transfections. This was accomplished by minorly changing the protocols for the DNA purification. Instead of using a standard column DNA purification kit, a crude DNA purification was done instead. This …
Collaborative Chemical Information Literacy: Is It "Scholarly?", Barbara C. Harvey
Collaborative Chemical Information Literacy: Is It "Scholarly?", Barbara C. Harvey
Barbara C. Harvey
This symposium illustrates a collaborative classroom activity that incorporates information literacy into an introductory chemistry course. The primary learning outcomes of the activity are to understand the peer-review process, knowing how to locate original research articles based on “clues” in a general news article, and how to differentiate between popular and scholarly periodicals. Students work in small groups in a highly-collaborative classroom setting. Each group is given a recent chemistry-related news item, and must determine how and where to find the original research article the news item is based on. Emphasis is placed on identifying original, peer-reviewed research publications. Each …
