TL;DR: In this paper, a label-free immunosensor for the detection of ochratoxin A (OTA) based on use of magnetic nanoparticles (MNPs) was developed, where a gold electrode was modified using bovine serum albumin conjugate with a glutaraldehyde-thiolamine linker, creating a layer that prevents non-specific binding of OTA on gold.
Journal ArticleDOI
A novel, sensitive, reusable and low potential acetylcholinesterase biosensor for chlorpyrifos based on 1-butyl-3-methylimidazolium tetrafluoroborate/multiwalled carbon nanotubes gel.
TL;DR: The novel, low potential and highly sensitive acetylcholinesterase biosensor developed based on 1-butyl-3-methylimidazolium tetrafluoroborate/multiwalled carbon nanotube composite gel thiocholine sensor exhibited a good stability and reproducibility and could be use for multiple determinations of pesticide with no loss of the enzyme activity.
Journal ArticleDOI
Acetylcholinesterase biosensor for carbamate drugs based on tetrathiafulvalene-tetracyanoquinodimethane/ionic liquid conductive gels.
TL;DR: The analysis of spiked tap water proved the acetylcholinesterase biosensor capability to be used as a screening method for detection of carbamate drugs in wastewaters.
Journal ArticleDOI
A rational design of the multiwalled carbon nanotube-7,7,8,8-tetracyanoquinodimethan sensor for sensitive detection of acetylcholinesterase inhibitors.
TL;DR: The biosensor developed by immobilization of acetylcholinesterase in sol-gel allowed the detection of two reference AChE inhibitors, paraoxon-methyl and chlorpyrifos with detection limits of 30 pM (7 ppt) and 0.4 nM (0.1 ppb), respectively.
Journal ArticleDOI
Advances in Electrochemical Impedance Spectroscopy Detection of Endocrine Disruptors.
TL;DR: Electrochemical impedance spectroscopy (EIS)-based sensors can be easily implemented in fully automated, sample-to-answer devices by integrating electrodes in microfluidic chips.
