An electrochemical DNA biosensor for trace amounts of mercury ion quantification

In this work we report the development of an electrochemical DNA biosensor with high sensitivity for mercury ion detection. A new matrix based on gold nanoparticles (AuNPs)-glutathione (GSH)/cysteine was investigated. The interaction between DNA oligonucleotides and Hg2+ ions followed by the formation of Thymine–Hg2+–Thymine (T–Hg2+–T) structures was quantified using different electrochemical ...

Pd/RGO modified carbon felt cathode for electro-Fenton removing of EDTA-Ni

Ethylenediaminetetraacetic acid (EDTA) forms stable complexes with toxic metals such as nickel due to its strong chelation. The electro-Fenton (EF) process using a cathode made from palladium ...

Voltammetry: Trace Level Determination of Cu, Pb, and Zn in Fish for Human Consumption

A research paper recently published by Jafari and Sobhanardakani in Current World Environment suggests voltammetry as a viable method for the determination of the heavy metals Cu, Pb, and Zn at trace levels in three different species of freshwater ...
