On the mechanical and electronic properties of thiolated gold nanocrystals.

High performance liquid chromatographic analysis of reduction products of a thiolated DNA for immobilization on gold nanoparticles

DNA-based nano-biosensors are emerging scope in the field of biosensors. Many synthetic single stranded functional DNAs have been applied for development of such sensors, recently. Immobilization of DNA oligonucleotides on the surface of gold nanoparticles is a key step in the development of most colorimetric nano-biosensors. The bound DNA is usually thiolated and forms Au-S covalent bond to th...

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...

SAM-like arrangement of thiolated graphene nanoribbons: decoupling the edge state from the metal substrate.

Density functional theory calculations have been used to analyze the electronic and magnetic properties of ultrathin zigzag graphene nanoribbons (ZGNRs) with different edge saturations. We have compared a symmetric hydrogen saturation of both edges with an asymmetric saturation in which one of the edges is saturated with sulphur atoms or thiol groups, while the other one is kept hydrogen satura...

Investigating the Effects of Some Capping Agents upon Gold Nanocrystals Stability, Size and Surface Plasmon Resonance

Synthesis, Molecular Docking and Cytotoxic Activity Evaluation of Organometallic Thiolated Gold(I) Complexes

The complex [(PhCH2NC)AuCl], 1, was prepared by the reaction of [(Me2S)AuCl], A, with an equimolar amount of benzyl isocyanide (PhCH2NC) ligand. Through a salt metathesis reaction, the chloride ligand in 1 was replaced by potassium benzothiazole-2-thiolate (Kbt) and potassium benzoimidazole-2-thiolate (Kbi) to a...
