Abstract

An effective and facile approach for the preparation of multilayered nanostructure of gold nanorods is demonstrated. The strategy presented here to construct three-dimensional nanostructure of Au nanorods (NRs) is quite facile and easy control, which opens up a routeway to the future application of Au NRs in nanodevices as well as in molecular detection.

Abstract

A useful method is developed for the synthesis of various gold nanostructures and the surface-enhanced Raman scattering (SERS) spectra of 4-aminothiophenol (4-ATP) on the as-prepared gold nanostructures of various shapes are measured. The evaluation suggests that intensity of the SERS signal is the smallest for the gold nanosheets and the flowerlike nanoparticle arrays have given the strongest SERS signals.

Abstract

A simple procedure to assemble gold nanoparticles into hallow tubular morphology with micrometer scale is described, wherein the citrate molecule is used not only as a reducing and capping agent, but also as an assembling template. The results reveal that the microtubes both before and after electroless plating could be used as surface-enhanced Raman scattering (SERS) substrates and the microtubes after electroless plating have displayed excellent enhancement ability.

Abstract

The synthesis, characterization and spectra properties of the wire-like ZnS/cyclohexylamine (CHA) nanocomposite are reported. The pure hexagonal wurzite ZnS nanowires are obtained by extracting the ZnS/CHA nanocomposites with dimethyl formamide (DMF).

Abstract

A noncovalent method of modifying multiwalled carbon nanotubes (MWNTs) was developed by embedding the nanotubes within polysiloxane micelles. On the basis of MWNTs, negatively charged gold nanoparticles are anchored to the nanotube surface through electrostatic interactions between the protonated amino groups and the gold nanoparticles.

Abstract

An effective and facile in situ reduction approach for the fabrication of carbon nanotube-supported Au nanoparticle (CNT/Au NP) composite nanomaterials is demonstrated. Linear polyethyleneimine (PEI) is ingeniously used as both a functionalizing agent for the multiwalled carbon nanotubes (MWNTs) and a reducing agent for the formation of Au NPs.
