Electrochemical Microsensors for the Detection of Cadmium(II) and Lead(II) Ions in Plants
Routine determination of trace metals in complex media is still a difficult task for many analytical instruments. The aim of this work was to compare three electro-chemical instruments [a standard potentiostat (Autolab), ...
Modification of working electrode surface with carbon nanotubes as an electrochemical sensor for estimation of melting points of DNA
(Elsevier BV, 2009-09-06)
Screen-printed with three electrode system was used in this study. A working electrode has been printed from carbon nanotubes based paste on silver layer modified with nano-patterned structures for the first case. In the ...
Bio-Sensing of Cadmium(II) Ions Using Staphylococcus aureus
Cadmium, as a hazardous pollutant commonly present in the living environment, represents an important risk to human health due to its undesirable effects (oxidative stress, changes in activities of many enzymes, interactions ...
Silver(I) Ions Ultrasensitive Detection at Carbon Electrodes-Analysis of Waters, Tobacco Cells and Fish Tissues
We used carbon paste electrodes and a standard potentiostat to detect silver ions. The detection limit (3 Signal/Noise ratio) was estimated as 0.5 mu M. A standard electrochemical instrument microanalysis of silver(I) ions ...
An Acetylcholinesterase-Based Chronoamperometric Biosensor for Fast and Reliable Assay of Nerve Agents
The enzyme acetylcholinesterase (AChE) is an important part of cholinergic nervous system, where it stops neurotransmission by hydrolysis of the neurotransmitter acetylcholine. It is sensitive to inhibition by organophosphate ...
