Direct coating of mesoporous titania on CTAB-capped gold nanorods.
We demonstrate a CTAB-templated approach towards direct coating of mesoporous titania on gold nanorods in aqueous solutions. The formation of the mesoporous shell is found to be closely correlated with CTAB concentration and the amount of the titania precursor. This approach can be readily extended to form mesoporous titania shells on other CTAB-capped nanoparticles.
متن کاملContinuous flow synthesis of citrate capped gold nanoparticles using UV induced nucleation
A new approach for synthesising gold nanoparticles of controlled size in the presence of trisodium citrate is presented. UV light is employed as a photoinitiator for the reduction of Au(III) by citrate. The UV induced nucleation takes place in a glass capillary tube (0.8 mm internal diameter) illuminated by a series of germicidal UVC lamps. This has been coupled sequentially with a heated coil ...
متن کاملSurface plasmon resonance and magnetism of thiol-capped gold nanoparticles.
Surface plasmon resonance measurements and magnetic characterization studies have been carried out for two types of thiol-capped gold nanoparticles (NPs) with similar diameters between 2.0 and 2.5 nm and different organic molecules linked to the sulfur atom: dodecanethiol and tiopronin. In addition, Au NPs capped with tetraoctyl ammonium bromide have also been included in the investigation sinc...
متن کاملDisk micelles from amphiphilic Janus gold nanoparticles.
Janus gold nanoparticles are synthesised via a simple preparation method and behave as amphiphiles self-assembling in water into disk-shaped micelles.
متن کاملCitrate capped superparamagnetic iron oxide nanoparticles used for hyperthermia therapy
Superparamagnetic magnetite nanoparticles (MNP) of about 10 nm were designed with proper physicochemical characteristics by an economic, biocompatible chemical co-precipitation of Fe and Fe in an ammonia solution, for hyperthermia applications. Synthetic methodology has been developed to get a well dispersed and homogeneous aqueous suspension of MNPs. Citric acid was used to stabilize the magne...
