    Ligation LAMP Assay Targeting miRNA-155 Biomarker for Diagnosing Acute Myeloid Leukemia Mark Vitievsky, Logan Buckmon, Soma Hebbar, Jason Berdia Acute Myeloid Leukemia (AML) is a severely dangerous form of blood cancer with high mortality rates, in part due to limitations in current diagnostic methods, which are invasive, expensive, and time-consuming. This study uses a ligation LAMP (loop-mediated isothermal amplification) assay as a possible new diagnostic tool which targets the overexpression of the miRNA-155 biomarker, which is known for its role in immune suppression in AML. The Ligation-LAMP assay offers a rapid, cost-effective, and minimally invasive alternative to the traditional methods of diagnosis, such as bone marrow biopsies or blood counts. This project evaluates the sensitivity and specificity of the Ligation LAMP assay using both fluorescent and colorimetric standards to detect varying concentrations of miRNA-155. Early findings show that higher levels of miRNA-155 correlate to faster fluorescence and colorimetric changes, in turn validating the assay’s potential for earlier AML detection. Future enhancements include the implementation of machine learning algorithms to hone in on the diagnostic thresholds, testing patient samples to address variability, and improving assay reliability. This project represents a step forward in the development of accessible and relatively inexpensive diagnostic tools for AML, providing the possibility of earlier diagnosis and improved patient livelihoods.

    Lab-on-CMOS-Capacitance Sensor Array for Real-Time Cell Viability Measurements
    (2024) Dasgupta, Prithwish; Nielsen, Kyle; Abshire, Pamela
    This project addresses the need to enhance the functionality and reusability of existing CMOS chips for monitoring cell viability and facilitating visual inspection. The primary challenge tackled is the reduction of research downtime due to inefficient sensor replacement and the improvement of data collection methods. To achieve this, the project integrates PCB design software, CAD software, and programming languages, including VHDL, C, and MATLAB. PCB design is utilized to create strategic board configurations aimed at streamlining the data collection process and ensuring the creation of a reliable and replaceable cell viability measurement device. These methods synergistically enhance CMOS chip functionality and usability, with a focus on streamlining packaging, facilitating hot-swappable system development, and establishing a data readout system. Key achievements encompass the development of a hot-swappable system for effortless CMOS chip replacement, streamlined packaging to bolster chip longevity, and the establishment of a real-time data readout system. These advancements notably enhance research efficiency and data quality by minimizing downtime and improving the correlation of capacitance measurements with direct visual observations of cell behavior. In the broader context of lab-on-a-chip technology and sensor development, these achievements deepen our understanding of cell behavior and expedite progress in drug screening, disease diagnostics, and tissue engineering. The integrated approach presented in this research marks a significant advancement in pushing the boundaries of lab-on-a-chip technology and its applications in biomedical research.
