Surface modification of gold nanorods through a place exchange reaction inside an ionic exchange resin.
نویسندگان
چکیده
A place exchange reaction between 11-mercaptoundecanoic acids (MUA) and cetyltrimethylammonium bromide (CTAB)-protected gold nanorods (GNRs) was conducted inside an ionic exchange resin; this modification resulted in functional gold nanorods soluble in both polar and nonpolar organic solvents.

Citrate-Stabilized Gold Nanorods
Stable aqueous dispersions of citrate-stabilized gold nanorods (cit-GNRs) have been prepared in scalable fashion by surfactant exchange from cetyltrimethylammonium bromide (CTAB)-stabilized GNRs, using polystyrenesulfonate (PSS) as a detergent. The surfactant exchange process was monitored by infrared spectroscopy, surface-enhanced Raman scattering (SERS), and X-ray photoelectron spectroscopy (...
متن کاملSynthesis of ordered mesoporous crystalline CuS and Ag2S materials via cation exchange reaction.
Cation exchange reaction is a strong tool for the synthesis of new ionic nanomaterials. Most of them are isolated nanoparticles with simple geometric features, such as nanodots, nanorods and nanospheres. In this work, we demonstrated that ordered mesoporous CdS with a complex cubic Ia3d gyroidal 3D bicontinuous porous structure and large particle size can be successfully converted to crystallin...
متن کاملEsterification Reaction Kinetics Using Ion Exchange Resin Catalyst by Pseudo-Homogenous and Eley-Ridel Models
This work deals with kinetics and chemical equilibrium studies of esterification reaction of ethanol with acetic acid. The esterification reaction was catalyzed by an acidic ion exchange resin (Amberlyst-15) using a batch stirred tank reactor. The pseudo-homogenous and Eley-Rideal models were successfully fitted with experimental data. At first, Eley-Rideal model was examined for heterogeneous...
متن کاملModification of gold nanoparticle surfaces with pyrenedisulfide in ligand-protected exchange reactions
We provide a study of ligand place-exchange reaction on Au nanoparticles. Nanoparticles of the dimensions of 7–9 nm were fabricated by high-temperature anhydrous route in the presence of primary aliphatic amine. The advantage of weak coordination to gold, through the nonbonding electrons of the amino group, was to use in an exchange of an initial protective ligand. Therefore, among other stabil...
متن کاملThin Film Heterogeneous Ion Exchange Membranes Prepared by Interfacial Polymerization of PAA-co-Iron-Nickel Oxide Nanoparticles on Polyvinylchloride Based Substrate
In this research thin film heterogeneous cation exchange membrane was prepared by interfacial polymerization of polyacrylic acid-co-iron nickel oxide nanoparticle son PVC based substrate. Spectra analysis confirmed graft polymerization conclusively. The SEM images showed that polymerized layer covers the membranes by simple gel network entanglement. Results exhibited that membrane water content...
