Creating Unique Chemistries within Porous Silicon Platforms & Piezoelectric Inkjet Printed Glucose Biosensor Based on Protein and Luminophore Doped Hybrid Xerogels Collado, Crystal Bright, Frank Chemistry analytical chemistry Ph.D. This dissertation discusses two areas of research with analyte-dependent photoluminescence (PL) response as the commonality. Part I demonstrates that gallium indium (GaIn) eutectic can be used to create interesting crystalline Si/porous silicon (cSi/pSi) platforms that exhibit unique analyte-and spatially-dependent PL responses. Here, the cSi/pSi regions are characterized by using profilometry, scanning electron microscopy (SEM), wide-field PL microscopy, Fourier transform infrared (FTIR) microscopy, and Raman spectroscopy. White light mediated hydrosilylation, with various hydrosilylating agents, is explored to determine optimal stability and response. Furthermore, FTIR is used to assess depth of penetration of each hydrosilylating agent. Part II discusses piezoelectric inkjet printing (PIP) as a three dimensional (3D) printing technique to optimize glucose biosensors. The overall performance of PIP biosensors is evaluated in comparison to contact pin-printing (CPP) platforms. Additionally, confocal PL microscopy is utilized to more fully characterize the CPP and PIP glucose biosensor platforms. **To request an accessible version of the file(s) associated with this item, contact library@buffalo.edu.
