Zntppea As A Potential Photosensitizer In Photodynamic Therapy, Marly Welborn, Joseph E. Bradshaw

Scholars Day Conference

Photodynamic therapy (PDT) is an emerging treatment that is used against certain types of cancer and other diseases. It functions using a photosensitizer in the presence of light that contributes to cell death in the desired tissues. This research centered on the development of a novel water-soluble porphyrin that could be utilized as a photosensitizer. Using ethanolamine the resulting compound, ZnTPP-EA, was created. Purification and characterization was carried out. The ZnTPP-EA was tested on the A549 lung cancer cell line using an MTT assay under light and dark conditions to assess the compound's effectiveness as a photosensitizer for PDT.

Effects Of Storage Conditions On Bpa Leanching From Infant Oral Hygiene Products Using Fluorescence Spectroscopy, Emma Bynum, Sara Hubbard

Scholars Day Conference

Bisphenol-A (BPA) is a structural component in many plastic products, which acts as an endocrine-disruptor mimicking estrogen. This hormonal disruption has been linked to obesity, reproductive issues, cardiovascular problems, and neurodevelopment disorders. Infants are at the highest risk of BPA exposure compared to any other stage of life. Because an infant's endocrine system is developing, exposure to an endocrine-disruptor, such as BPA, can be especially harmful. While the FDA monitors products like baby bottles, canned goods, and plastic containers for BPA, infant oral hygiene products are not closely monitored.

Previous research in our lab used fluorescence spectroscopy to test several …
