Electrochemical biosensor for pesticides based on acetylcholinesterase immobilized on polyaniline deposited on vertically assembled carbon nanotubes wrapped with ssDNA.
The self-assembled monolayers of single walled carbon nanotubes wrapped by thiol terminated single strand oligonucleotide on gold was utilized to prepare nano size polyaniline matrix for acetylcholinesterase (AChE) enzyme immobilization. Expand
On the Mechanism of Unexpected Potentiometric Response to Neutral Phenols by Liquid Membranes Based on Quaternary Ammonium SaltsSystematic Experimental and Theoretical Approaches
Changes in membrane potentials (potentiometric responses) induced by undissociated, neutral phenols (ArOH), though unexpected in terms of the conventional response mechanism for charged species, wereExpand
Comparison of electrochemical immunosensors based on gold nano materials and immunoblot techniques for detection of histidine-tagged proteins in culture medium.
In this work, the direct electrochemical determination of poly-histidine tagged proteins using immunosensor based on anti-His (C-term) antibody immobilized on gold electrodes modified withExpand
Novel voltammetric biosensor for determining acrylamide in food samples.
Recent findings showing that acrylamide is formed in heat-treated foods rich in asparagine and reducing sugars such as glucose, have accelerated the needs for the development of new analyticalExpand
A Voltammetric Biosensor Based on Glassy Carbon Electrodes Modified with Single-Walled Carbon Nanotubes/Hemoglobin for Detection of Acrylamide in Water Extracts from Potato Crisps
The use of glassy carbon electrodes coated with single-walled carbon nanotubes and Hb for voltammetric detection of acrylamide in water solutions and validation made in the matrix obtained by water extraction of potato crisps showed that the electrodes presented are suitable for the direct determination of acrieslamides in food samples.

Electrochemical genosensor based on disc and screen printed gold electrodes for detection of specific DNA and RNA sequences derived from Avian Influenza Virus H5N1
Abstract The genosensors based on thiolated ssDNA probe deposited on the two types of gold electrodes: screen-printed (miniaturized) and disc electrodes destined for determination of specificExpand
Electrochemical immunosensor for detection of antibodies against influenza A virus H5N1 in hen serum.
The immunosensor proposed was able to detect antibody in hen serum diluted up to 7 × 10(7)-fold and the sensitivity was about four orders of magnitude much better than ELISA. Expand
An Immunosensor Based on Antibody Binding Fragments Attached to Gold Nanoparticles for the Detection of Peptides Derived from Avian Influenza Hemagglutinin H5
The immunosensor was able to recognize three different His-tagged variants of recombinant hemagglutinin from H5N1 viruses, and the strongest response has been observed for the long variant with detection limit of 2.2 pg/mL and dynamic range from 4.0 to 20.0 pg/ mL. Expand
Electrochemical biosensors for detection of avian influenza virus--current status and future trends.
This review critically review the detection of avian influenza virus in the complex matrices that use electrochemical biosensors and compare them with traditionally applied methods such as ELISA or Western blot. Expand
Voltammetric Detection of S100B Protein Using His-Tagged Receptor Domains for Advanced Glycation End Products (RAGE) Immobilized onto a Gold Electrode Surface
The proposed biosensor was quite sensitive, with a detection limit of 0.52 pM recorded in the buffer solution, and the presence of diluted human plasma and 10 nM Aβ1-40 have no influence on the biosensor performance. Expand
