Imaging The Tumor Microenvironment Using 1,2-Dioxetane Chemiluminescence Agents, Lucas Ryan

Chemistry Theses and Dissertations

As complex organisms, animals and humans rely on a delicate interplay between many connected systems to maintain proper cellular and whole-body function. Oxygen regulation and homeostasis are vital for proper function in healthy cells, as are core components of aerobic metabolism and efficient ATP generation to supply our energy needs. Maintaining pH homeostasis is also of primary importance; cells maintain pH homeostasis through a host of active and passive transporters to maintain pH balance both inside and outside of the cell.

Events of uncontrolled cellular proliferation, also known as cancer, survive and thrive under conditions that perturb the delicate balance …

I. Non-Degradable Polysiloxane Networks For Controlled Release Applications, And Ii. Additive Free, Degradable Silyl-Ether Furyl-Maleimide Networks, Caleb M. Bunton

Chemistry Theses and Dissertations

I. Two different series of non–degradable polysiloxane networks were prepared for the encapsulation and controlled release of a small molecule agent. For the first series, hydrosilylation was utilized to prepare networks of varying crosslink densities, as determined from swelling studies, from vinyl terminated and silylhydride functional poly(dimethyl)siloxanes. For the second series, the thiol-ene reaction was utilized to prepare networks of varying crosslink densities, as determined from swelling studies, from vinyl terminated and mercaptopropyl functional poly(dimethyl)siloxanes. Nile red dye was used as an encapsulated agent and dye release from each series of networks was measured using UV–vis spectroscopy to determine controllability …
