Hyper-Rayleigh scattering of gold nanorods and their relationship with linear assemblies of gold nanospheres.
The surface plasmon enhanced hyper-Rayleigh scattering light collected from an aqueous solution of gold nanorods is reported. A non negligible part of the signal is attributed to a photoluminescence background attributed to the electron hole recombination following multiphoton excitation of d-valence band electrons into the sp-conduction band. This radiative relaxation process is likely favored...
متن کاملFacile phase transfer of gold nanorods and nanospheres stabilized with block copolymers
A fast route to transfer Au nanoparticles from aqueous to organic media is proposed based on the use of a high molecular mass diblock copolymer of styrene and 2-vinylpyridine for ligand exchange at the nanoparticle surface. The method enables the preparation of stable sols of Au nanorods with sizes of up to tens of nanometers or Au nanospheres in various organic solvents. By comparing the optic...
متن کاملQuantitative Comparison of Photothermal Heat Generation between Gold Nanospheres and Nanorods
Gold nanoparticles (GNPs) are widely used for biomedical applications due to unique optical properties, established synthesis methods, and biological compatibility. Despite important applications of plasmonic heating in thermal therapy, imaging, and diagnostics, the lack of quantification in heat generation leads to difficulties in comparing the heating capability for new plasmonic nanostructur...
متن کاملorganophosphate pesticide in Beagle dogs
Organophosphate compounds, which are potent irreversible inhibitors of carboxylic esterases, including cholinesterase, have been extensively used as pesticides throughout the world, and many unfortunate incidents of acute intoxication have been reported (Grob and Harvey, I953; Goldman and Teitel, I958; Healy, 1959; Dinman, I964; Quinby, I964; Crowley and Johns, I966; DePalma, Kwalick, and Zuker...
متن کاملEvaluation of effect of gold nanorods and spherical gold nanoparticles of different sizes on X-ray attenuation in computed tomography
Introduction: To date, gold nanoparticles (GNPs) have been demonstrated to have great potential as contrast agent for CT imaging and therapeutics. This study was designed to evaluate any effect on X-ray attenuation that might result from using GNPs with a variety of size, surface chemistries and shapes. Materials and Methods: Spherical GNPs and gold nanorod...
