However, carbon nanoparticles are more cost effective and readily available carbon-based nanomaterials that can be used for a wide range of applications. This thesis focuses on the plasmonic enhancement of hematite nanostructured photoanodes through the novel use of AuSiO2Au core-shell-shell (CSS). Core-shell type gold nanoparticles of a few nanometer core size with organic. This class of nanomaterial is generally outclassed by modern and more fashionable carbon nanotubes and graphene-based systems. The nanodots are demonstrated to have the potential to be developed into nanomedicines and biocompatible scaffolds for new drug delivery mechanisms.These straightforward synthesis, modification, and application methods demonstrate the effectiveness and the versatility of carbon nanoparticles. These nanodots exhibit two-photon fluorescence that is exhibited both in solution and in HeLa cells. Herein, the facile synthesis of C-dots that possess intrinsic pyridine functionality is described. This functionality is subjected to synthetic methods to obtain carbon nanoparticles with extremely hydrohphobic character, which are demonstrated as important substrates for probing lipophilic redox systems and lipid character under different experimental conditions.Fluorescent carbon nanodots (C-dots) are another important form of carbon nanoparticle. This methodology results in carbon nanoparticles with surface boronic acid functionality that is demonstrated to be affective in the electrochemical detection of catecholic caffeic acid.Emperor 2000 carbon nanoparticles are commercially produced with phenylsulphonic acid functional groups on the surface. These interactions are exploited to append pyrene-based compounds onto the surface of the carbon nanoparticles. The surface of Emperor 2000 is shown to be susceptible to physisorption, through π-π stacking. Emperor 2000, a commercial bulk-produced carbon black available from Cabot Corporation, is the starting material for many of the investigations. This thesis focuses on the synthesis and surface modification of different carbon nanoparticles and each novel nanomaterial is demonstrated to have a specific sensing application.Carbon blacks play a significant role in the research that is presented herein. ![]() Finally, the research focuses on facile approaches to engineer the transition of the temperature-sensitive particles and develop composite core-shell nanoparticles with a metallic shell.AbstractCarbon nanoparticles constitute a class of important materials that have uses in many different fields. This masters thesis details the synthesis of a dual core/shell contrast for imaging in both modes, created by using a core of iron oxide and a outer shell. Similarly, by incorporating poly-2-(N,N)-dimethylamino)ethyl methacrylate (PDMA) into the core, pH sensitive core-shell composite nanoparticles were synthesized and applied as effective carriers to release a rheological modifier upon a pH change. The composite nanoparticles were temperature sensitive and could be up-taken by human prostate cancer cells and demonstrated effectiveness in drug delivery and cancer therapy. More importantly, Pickering emulsion polymerization was employed to synthesize polystyrene/poly(N-isopropylacrylamide) (PNIPAAm)-silica core-shell nanoparticles with N-isopropylacrylamide incorporated into the core as a co-monomer. The silica nanoparticles were thermodynamically favorable to self-assemble at liquid-liquid interfaces at the initial stage of polymerization and remained at the interface to finally form the shells of the composite particles. Possible mechanisms of the Pickering emulsion polymerization were also explored. Title: Synthesis and characterization of semiconductor type I core shell nanoparticles and their interaction with biomolecules. The one-step Pickering emulsion polymerization method was successfully developed and applied to synthesize polystyrene-silica core-shell composite particles. This is an interesting class of supramolecular building blocks and can "exhibit unusual, possibly unique, properties which cannot be obtained simply by co-mixing polymer and inorganic particles". This dissertation focuses on the study of core-shell type of nanoparticles where a polymer serves as the core and inorganic nanoparticles are the shell. Among them, core-shell composite nanoparticles are an important class of materials which are attractive for their applications in catalysis, sensing, electromagnetic shielding, drug delivery, and environmental remediation. Nanoparticles are ubiquitous in various fields due to their unique properties not seen in similar bulk materials. The Synthesis of Core-Shell IronGold Nanoparticles and Their. In the first third of this thesis, magnetic core gold shell nanoparticles are incorporated into a novel platform for the delivery of a potent anti-cancer. ![]()
