Development Of A Rapid Diagnostic Assay For The Colorimetric Detection Of Bacterial And Viral Pathogens Using Loop-Mediated Isothermal Amplification Coupled With A Peptide Nucleic Acid And Gold Nanoparticle Reporter System, William Brown
All NMU Master's Theses
Detection of pathogenic agents remains pivotal to the control and prevention of infectious disease. While diagnostic methods continue to break barriers, the need for accurate, sensitive, and rapid methods persists. Current methods for pathogen detection, including culture, immunochemical, or molecular-based techniques, are subject to significant limitations that restrict their clinical utility. Point-of-care (POC) tests have received attention for the diagnostic screening of infectious disease, with benefits of simplicity, affordability, and convenience. This study describes the development of a novel loop-mediated isothermal amplification (LAMP) reaction followed by a peptide nucleic acid (PNA) probe and gold nanoparticle (AuNP) detection system that results …

A Rapid Colorimetric Peptide Nucleic Acid Loop-Mediated Isothermal Amplification Assay For The Detection Of The Idh1 Mutation In Glioblastoma, Edward J. Raack
All NMU Master's Theses
The IDH1 mutation is an important diagnostic and prognostic biomarker used to characterize glioblastoma (GBM). Patients harboring the IDH1 mutation have improved overall survival following maximal resection. Knowledge of the IDH1 mutation status allows the surgeon to modify the surgical plan; however, no existing molecular test can provide this information intraoperatively. We designed a novel colorimetric peptide nucleic acid loop-mediated isothermal amplification (PNA-LAMP) method that rapidly detects the IDH1 R132H mutation in GBM. PNA-LAMP amplifies target DNA under isothermal conditions with high specificity and speed. The PNA prevents amplification of wild-type IDH1 DNA, while allowing amplification of the R132H variant …
