Cellulose is a strong, readily available biologically sourced polymer with a wide potential for applications in many fields. Its high degree of biodegradability makes it an excellent candidate for environmentally friendly sensors, but it is necessary to devise a method by which to render it conductive. Silver nanowires are highly conductive nanoparticles with many potential applications in sensing, as well as being on a similar order-of-magnitude in size as cellulose derivatives, which makes them a prime candidate for use in this application. Methods of casting cellulose nanofibrils (CNF), cellulose nanocrystals (CNC), and TEMPO-Oxidized CNF (TEMPO CNF) films were explored, and …

The University of Maine is one of the world’s leading producers of cellulose nanofibers (CNF). This material has the power to revitalize the Maine paper industry. This has led to an abundance of labs on campus researching applications for the material. Active research activities at the University of Maine include industrial applications such as filtration, biodegradable packaging, building materials and niche health care applications. Niche health care applications include wicking pads for point of care diagnostics and tunable biomaterials ranging from dressings to implantable bone-like materials. Medical applications require an analysis of the biocompatibility of CNF.CNF is biocompatible in general: …

Magnetic Resonance Imaging (MRI) relies heavily on contrast agents such that diagnosis of various diseases can be made with increased confidence. Current contrast agents for MRI depend on various chelated molecules composed of a toxic gadolinium ion, Gd3+. In 2006, a discovery was made connecting Nephrogenic Systemic Fibrosis (NSF) and these gadolinium based contrast agents (GBCAs). The connection between life threatening NSF and GBCAs stems from patients with pre-existing kidney malfunctions. It has been proposed that an alternative agent such as iron oxide nanoparticles (IONPs) be investigated. These IONPs theoretically will have similar responses in efficiency of improving …
