Studies of the interaction of the relevant metal, metalloid or nanoparticulate species with biological systems are underpinned by the provision of reliable information about chemical composition of the relevant materials. Often, no methods of chemical analysis are available. The work described in this dissertation centers on developing methods to help with studies for a variety of analytes and samples. A method was developed for the determination of 11 trace elements (As, Cd, Co, Cr, Cu, Fe, Mg, Mn, Pb, Ti, and Zn) in human breast milk and infant formulas by inductively coupled plasma optical emission spectrometry (ICP-OES) following microwave-assisted digestion. …

Open Access Dissertations
Over the past few decades, tremendous efforts have been made to develop nanomaterials for biotechnological applications such as therapeutics. Understanding and engineering interfaces between biomacromolecules and nanomaterials is a key to the creation of successful therapeutic systems. My research has been oriented toward developing therapeutic systems using gold nanoparticles (AuNPs) incorporating material science, organic synthesis, and biology. For this purpose, mixed monolayer protected AuNPs (~2 nm core size) with various functional groups have been employed for triggering therapeutic effects. Several strategies have been accomplished using anticancer drugs that non-covalently and covalently incorporate onto AuNPs as a drug delivery carrier. Alternatively, …
