This Final Design Review (FDR) document outlines the senior design project implemented by a team of three mechanical engineering students at California Polytechnic State University, San Luis Obispo for a professor in the biochemistry and chemistry department, Dr. Javin Oza. The project involved designing and manufacturing a portable ultraviolet fluorescence illuminator that will indicate the fluorescent glow of biomaterials for viewing purposes. The goal was to create a portable product out of recyclable material that can be used in field applications and increase accessibility to affordable science equipment. The initial sponsor and user interviews, technical background research, product research, and …

Determining A Method For Rendering Low Cost Cdse(Zns) Core(Shell) Quantum Dots Aqueous Soluble Via Amphiphilic Polymer Wrapping, Patrick Mcbride
Materials Engineering
Herein is described the procedure of two amphiphilic polymer wrapping techniques that may be employed for obtaining aqueous soluble quantum dots (QDs) for use in biological fluorescent imaging applications. The advent of QDs has led to new nanoscale fluorescent materials that exhibit unparalleled quantum yields (QYs), high resistance to photobleaching, tunable emissions, and
absorption over a large optical range. However, the QD synthesis employed here at Cal Poly to obtain bright, photostable CdSe(ZnS) core(shell) QDs involves the use of organic solvents and surfactants, leading to hydrophobic QDs. Since all of biology relies on aqueous solubility, this hydrophobicity creates a major …
