Improving Cellphone-Based Bio-Imaging Technique For Fluorescence Detection, Erteza T. Efaz
Improving Cellphone-Based Bio-Imaging Technique For Fluorescence Detection, Erteza T. Efaz
LSU Master's Theses
The research presented in this thesis focuses on the design, development, and evaluation of a fluorescence detection system. The system is implemented primarily as an Android application, Auto Camera, which leverages smartphone cameras to capture and analyze fluorescent images. The application provides a user-friendly interface with some configurable features like exposure time, ISO speed, and storage limit; as well as defining detection thresholds and setting acquisition intervals. This study begins with the architectural framework of the Android application, which is written in Java using Android Studio. The API compatibility is set to version 33, and users are prompted to grant …
Hyperspectral Imaging For Characterizing Single Plasmonic Nanostructure And Single-Cell Analysis, Nishir Sanatkumar Mehta
Hyperspectral Imaging For Characterizing Single Plasmonic Nanostructure And Single-Cell Analysis, Nishir Sanatkumar Mehta
LSU Master's Theses
Orientation of plasmonic nanostructures is an important feature in many nanoscale applications such as photovoltaics, catalyst, biosensors DNA interactions, protein detections, hotspot of surface-enhanced Raman spectroscopy (SERS), and fluorescence resonant energy transfer (FRET) experiments. Silver nanocubes with significant spectral signatures between 400-700 nm are observed in this experimental research. Whereas study of single cells will enable the analysis of cell-to-cell variations within a heterogeneous population. These variations are important for further analysis and understanding of disease propagation, drug development, stem cell differentiation, embryos development, and how cells respond to each other and their environment. Adipose-derived mesenchymal stem cells possess the …

The Fabrication Of High-Aspect Ratio Gratings For Talbot Interferometer With Medical Imaging Application., Vikaram Singh
LSU Master's Theses
X-ray Phase contrast-based Talbot interferometer creates high contrast between weak and strong absorbing materials, which makes it effective in imaging soft tissues. However, its performance is bounded by the aspect-ratio, features and symmetry of its gratings. For 40 KeV energy X-rays, the analyzer grating thickness should be 100 µm or more to achieve > 90% absorption in order to obtain high contrast images. Moreover, the smaller period in grating is desired for higher resolution. Therefore, researchers are exploring various fabrication techniques to achieve greater aspect-ratio gratings. Utilizing modern LIGA techniques, the aspect-ratio of gratings can be improved with a simplified …
