Autocatalytic Electroless Silver Deposition Using 2-Aminoethanethiol as Reducing Agent.

Green Synthesis of Silver Nanoparticles Using Mentha aquatic L Extract as the Reducing Agent

Background: Developing effective methods for the synthesis of bio-compatible and non-toxic nanoparticles is the main goal of nanotechnology. In the most chemical methods, a chemical reducing agent is used to reduce metal ions. But, in chemical methods, the stability of nanoparticles is controversial and synthesis in large sizes is much more difficult. Moreover, there is an incr...

Silver deposition in the cervix after application of silver nitrate as a cauterising agent.

Large amounts of metallic silver pigment were found in 10 cervical biopsy specimens taken for the histological grading of cervical intraepithelial neoplasia (CIN). The assessment of CIN was made much harder because the pigment obscured the morphological detail of the epithelial cells, and in some it was very difficult to determine whether koilocytosis or CIN I was present. The silver can easily...

Copper electroless plating in weakly alkaline electrolytes using DMAB as a reducing agent for metallization on polymer films

Copper electroless plating at low pH (7–9) using dimethylamine borane complex as a reducing agent is studied electrochemically by linear sweep voltammetry, cyclic voltammetry and chronopotentiometry in full electrolytes. We find that the mixed potential theory is not applicable to the described system. We show that both the working potential and the rate-controlling mechanism are dependent on t...

Efficient SERS substrates made by electroless silver deposition into patterned silicon structures

A nano fabrication process using caesium chloride in an island lithography scheme has been used to make wells in a silicon dioxide layer on silicon. Silver structures have been made in these wells using an electroless process that involves the reduction of silver ions and oxidation of silicon in the presence of fluoride ions. The silver deposition process is found to be diffusion controlled. Th...
