General description

Potassium dicyanoaurate(I) is an inorganic salt, soluble in water and sparingly soluble in alcohol. It is widely used as an electrolyte in the electrodeposition of gold on various substrates such as thin films and electrodes.

Application

Potassium dicyanoaurate(I) can be used:
  • To prepare gold nanowire array electrodes with fast charge transfer ability.
  • As a supporting electrolyte for the electrodeposition of gold in organic media.
  • To prepare polypyrrole-ClO4 gas sensors with fast response time and high sensitivity to volatile organic compounds.
  • In the electrochemical preparation of gold nanoparticle composites.

Electrospray ionization spectra of potential cyanide-containing gold-drug metabolites revealed additional, weak, unanticipated peaks at approximately twice the mass of the gold(I) and gold(III) cyanide complexes. The exact masses correspond to proton-linked bimetallic complexes, [H[Au(CN)(m)](2)](-), (m=2,4). Further investigation revealed a total

Quaternary ammonium salt has strong affinity with gold in cyanide solutions, but it is not readily stripped. Stripping with acidic thiourea solutions and air sparging shows promise. There are some reports on the process of thiourea stripping, but little about

Chloride permeation through the cystic fibrosis transmembrane conductance regulator (CFTR) Cl- channel is blocked by a broad range of anions that bind tightly within the pore. Here we show that the divalent anion Pt(NO2)42- acts as an impermeant voltage-dependent blocker

Biomimetic pathways for the oxidation of [Au(CN)(2)](-), a gold metabolite, and further cyanation of the gold(III) products to form Au(CN)(4)(-) were investigated using 13C NMR and UV-Visible spectroscopic methods. Hypochlorite ion, an oxidant released during the oxidative burst of immune

Previous attempts to identify residues that line the pore of the cystic fibrosis transmembrane conductance regulator (CFTR) chloride channel have utilized cysteine-substituted channels in conjunction with impermeant, thiol-reactive reagents like MTSET+ and MTSES-. We report here that the permeant, pseudohalide
