چکیده

An effective self-assembly route for construction of Pt(II)-bridged [3]rotaxane functionalized gold nanoparticles was developed through a stepwise introduction of Pt(II) coordination and gold-thiol binding in turn. The sequential self-assembly process can be quantitatively controlled and directly monitored by the naked eye.

Determination of mercury (II) by spectrophotometric method based on self assembly of gold nanoparticles

Due to the binding of the –COO- group with the mercury (II), gold nanoparticlesfunctionalized with glutathione can self-assemble to form a supermolecular network in the HAc-NaAc buffer solution. The aggregation of functionalized gold nanoparticles and mercury (II)caused the shift of maximum absorption peak of the UV-Vis spectrum from 520 nm to 609 nm.Based on this principle, a simple spectropho...

Construction of a Carbon Paste Electrode Based on Novel Thiolated Ligand Capped Gold Nanoparticles for Determination of Trace Amounts of Mercury(II)

In the present study, a simple electrochemical sensor for trace determination of Hg(II) ions in aqueous solutions was introduced. The proposed sensor was designed by incorporation of the 4-methyl-piperidine-carbodithioate capped gold nanoparticles (GNPs) into the carbon paste electrode (CPE), which provides a remarkably improved sensitivity for stripping voltammetric determination of Hg(II). Di...
