Hence, this manuscript focuses on developing. However, their low aqueous solubility and high volatility compromise their maximum potential, thus requiring the development of efficient supports for their delivery. Iron core-shell nanoparticles with different morphologies were obtained on a H-terminated Si(100) surface for the first time by electrodeposition at. The results have provided important insights into the design of interfacial reactivities via core–shell nanocomposites for magnetic, catalytic and biological applications. Recent years have witnessed a tremendous interest in the use of essential oils in biomedical applications due to their intrinsic antimicrobial, antioxidant, and anticancer properties. The interparticle ligand exchange– precipitation chemistry at the gold shell is to our knowledge the first example demonstrating the inter-shell reactivity for constructing thin films of Fe particles. In addition to evidence from TEM detection of the change in particle size, UV-Vis observation of the change in the surface plasmon resonance band, and XRD detection of disappearance of the magnetite diffraction peaks after coating the gold shell, the formation of the core–shell morphology was further confirmed by DCP-AES composition analysis of Au and Fe in the molecularly-mediated thin film assembly of Fe particles. The core–shell nanocomposites and assemblies have been characterized using TEM, XRD, XPS, FTIR, TGA, and DCP-AES techniques. The novelty of our assembly strategy is the exploitation of the ligand-exchange reactivity at the gold shells for the thin film assembly of the core–shell nanoparticles. Pre-synthesized and size-defined iron oxide nanoparticles were used as seeding materials for the reduction of gold precursors, which was shown to be effective for coating the iron oxide cores with gold shells (Fe The unique aspect of our synthesis is the formation of Fe core–shell nanoparticles with controllable surface properties. This paper reports findings of an investigation of the synthesis of monolayer-capped iron oxide and core ( iron oxide)–shell (gold) nanocomposite and their assembly towards thin film materials.
