Ordered arrays of nanoporous gold nanoparticles
A combination of a "top-down" approach (substrate-conformal imprint lithography) and two "bottom-up" approaches (dewetting and dealloying) enables fabrication of perfectly ordered 2-dimensional arrays of nanoporous gold nanoparticles. The dewetting of Au/Ag bilayers on the periodically prepatterned substrates leads to the interdiffusion of Au and Ag and the formation of an array of Au-Ag alloy ...
متن کاملEncapsulation of gold nanoparticles into self-assembling protein nanoparticles
BACKGROUND Gold nanoparticles are useful tools for biological applications due to their attractive physical and chemical properties. Their applications can be further expanded when they are functionalized with biological molecules. The biological molecules not only provide the interfaces for interactions between nanoparticles and biological environment, but also contribute their biological func...
متن کاملCiprofloxacin-protected gold nanoparticles.
The antibacterial drug ciprofloxacin (cfH) has been used to protect gold nanoparticles of two different mean diameters, 4 and 20 nm. The protection is complete with about 65 and 585 cfH molecules covering 4 and 15 nm particles, respectively. The nature of binding has been investigated by several analytical techniques. The nitrogen atom of the NH moiety of piperazine group binds on the gold surf...
متن کاملControlled growth of hexagonal gold nanostructures during thermally induced self-assembling on Ge(001) surface
Nano-sized gold has become an important material in various fields of science and technology, where control over the size and crystallography is desired to tailor the functionality. Gold crystallizes in the face-centered cubic (fcc) phase, and its hexagonal closed packed (hcp) structure is a very unusual and rare phase. Stable Au hcp phase has been reported to form in nanoparticles at the tips ...
متن کاملFacile synthesis, assembly, and immobilization of ordered arrays of monodisperse magnetic nanoparticles on silicon substrates.
This paper outlines the preparation of monodisperse MnFe(2)O(4) nanoparticles modified with omega-alkenyl moieties in a one-pot reaction, requiring no ligand-exchange step, followed by deposition of the resulting surfactant-coated nanoparticles onto a hydrogen-terminated silicon (111) wafer and covalent anchoring to the surface via UV-initiated bonding, creating a stable two-dimensional array o...
