Development of acetylcholinesterase immobilized CMD (Carboxymethyldextran) chip-based sensor for the detection of nerve agent simulant parathion

open access: yesCumhuriyet Science Journal, 2020
In this study, a carboxymethyldextran chip based sensor system is developed that selectively recognizes and binds nerve agent molecules used in chemical weapons. Nerve agents fall under the group of organophosphorus compounds and irreversibly inhibit the

Macrophage TNF-α mediates parathion-induced airway hyperreactivity in guinea pigs. [PDF]

open access: yes, 2013
Organophosphorus pesticides (OPs) are implicated in human asthma. We previously demonstrated that, at concentrations that do not inhibit acetylcholinesterase activity, the OP parathion causes airway hyperreactivity in guinea pigs as a result of ...

Cu2O nanoparticles for the degradation of methyl parathion

open access: yesBeilstein Journal of Nanotechnology, 2020
Methyl parathion (MP) is one of the most neurotoxic pesticides. An inexpensive and reliable one-step degradation method of MP was achieved through an aqueous suspension of copper(I) oxide nanoparticles (NPs). Three different NPs sizes (16, 29 and 45 nm),

Toxicity of sodium chloride and methyl parathion on the macrophyte Lemna minor (Linnaeus, 1753) with respect to frond number and chlorophyll [PDF]

open access: yesBiotemas, 2009
Duckweed, Lemna minor L., is a suitable plant model for toxicity evaluation of many contaminants due to its small size and rapid growth. Methyl parathion is a toxic compound which is utilized to eliminate aquatic insect larvae, among other purposes.

Micro-extraction, pre-concentration, and microfluidic-based separation of organophosphate insecticides followed by the miniaturized electrochemical detection system [PDF]

open access: yesBioImpacts
Introduction: A new analytical method based on the coupling of microextraction and microfluidics was developed and investigated for the pre-concentration, separation, and electrochemical detection of fenitrothion (FT) and parathion (PA) at the sub-ppm ...

Electrochemical Studies of LbL Films With Dawson Type Heteropolyanion Glassy Carbon Electrode Sensor Modified for Methyl Parathion Detection

open access: yesFrontiers in Materials, 2022
Rapid methyl parathion detection was measured using a fabricated glassy carbon electrode (GCE) sensor designed using the layer-by-layer (LBL) method. Multilayer assemblies were developed on the glassy carbon electrode by alternating depositions of anions
