Ultrasensitive detection of ineradicable and harmful antibiotic chloramphenicol residue in soil, water, and food samples.

Chloramphenicol (CAP) is a harmful antibiotic that inevitably enters our food chain through natural or manmade means. Its ineradicable residue pollutes soils and water, accumulates in plants and animal products, and eventually affects human health. An ultrasensitive method for detecting and monitoring CAP is therefore urgently required.

Lanthanum tin oxide-modified sensor electrode for the rapid detection of environmentally hazardous insecticide carbaryl in soil, water, and vegetable samples.

The growing population and global food demands have encouraged the use of pesticides to increase agricultural yields; however, the irrational use of pesticides threatens human health and the environment. Carbaryl (CRBL) is the most widespread insecticide and severely affects soil, water systems, and human health. Thus, it is crucial to monitor CRBL residues in the environment and vegetable samples.

Effect of the NiTeO phase in a NiTeO/expanded graphite composite on the electrochemical monitoring of metribuzin residue in soil and water samples.

Growing food demand and climate change have led to the development of various pest control agents to increase crop yields. Although pesticides help meet the food demand, they cause harm to human health and the environment. Metribuzin (MTBZ) is one of the common herbicides used for controlling weeds.

Synthesis and characterizations of iron antimony oxide nanoparticles and its applications in electrochemical detection of carbendazim in apple juice and paddy water samples.

This study reports a facile sonohydrolysis synthesis route to prepare the iron antimony oxide (FeSbO) nanoparticles for the trace level electrochemical sensing of fungicide carbendazim (CRBZ). As prepared FeSbO nanoparticles show a nano-cubes-like morphology with uniform distributions that crystallized in the tetragonal phase. The diffraction studies reveal that the FeSbO nanoparticles have high crystallinity and high purity.

Facile synthesis of single-crystalline Fe-doped copper vanadate nanoparticles for the voltammetric monitoring of lethal hazardous fungicide carbendazim.

The highly selective and sensitive electrochemical detection of highly toxic fungicide carbendazim (CBZ) by the iron (Fe)-doped copper vanadate (CuVO; CuV) is discussed. The Fe-doped copper vanadate (Fe-CuV) is prepared by the simple co-precipitation method followed by an annealing process which produced high crystallinity. The material properties of Fe-CuV are characterized by XRD, Raman spectrometry, XPS analysis, HRTEM, and SAED pattern.

Selective electrochemical detection of antidepressant drug imipramine in blood serum and urine samples using an antimony telluride-graphite nanofiber electrode.

A high-performance imipramine (IMPR) sensor has been developed  based on metal chalcogenide-carbon composite materials. The antimony telluride-graphite nanofiber (SbTe-GNF, hereafter SBT-GNF) composite was synthesized by the hydrothermal method and confirmed by X-ray powder diffraction (XRD) pattern. The morphology, crystalline lattice, and chemical states were characterized by HRTEM, SAED, and XPS analysis.

Preparation of K intercalated MnO-rGO composite for the electrochemical detection of nitroaniline in industrial wastewater.

This work reports the electrochemical detection of highly hazardous material 4-Nitroaniline (4-NA) based on the metal oxide-rGO composite materials. The potassium intercalated MnO-rGO composite material was prepared by a simple one-pot reduction method. The K intercalation on K-MnO-rGO was confirmed by X-ray photoelectron spectroscopy (XPS) and Raman analysis.

Sonochemical synthesis of samarium tungstate nanoparticles for the electrochemical detection of nilutamide.

This study reports the sonochemical synthesis of samarium tungstate nanoparticles (SWNPs) for applications in electrochemical sensors. The synthesis process is based on a precipitation reaction, which was investigated by ultrasound and compared with the effect of stirring. A bath sonicator operated at a frequency and power of 37/100 kHz and ~60 W, respectively, was employed to prepare the material.

Sonochemical preparation of bismuth oxide nanotiles decorated exfoliated graphite for the electrochemical detection of imipramine.

This work described the sonohydrolysis of Bi(NO) into BiO and simultaneous sonochemical exfoliation of graphite into graphene sheets in the alkaline environment and its electocatalytic performance towards the detection of anti-depression drug imipramine (IMPR). The ultrasound (37/80 kHz; 60 W) effectively hydrolyzed the Bi(NO) into a single crystalline monoclinic phase of BiO nanotiles in the alkaline condition. And also, the sonochemical reaction condition can trigger the lamellar particles on the graphite bulk surface and allowed to exfoliated the graphite (EG) into graphene nanosheets as well.

Structural Insights on 2D Gadolinium Tungstate Nanoflake: A Promising Electrocatalyst for Sensor and Photocatalyst for the Degradation of Postharvest Fungicide (Carbendazim).

Gadolinium tungstate (Gd(WO)) has acquired much attention owing to its exclusive transport properties and excellent thermal and chemical stability. In this work, we demonstrate that two-dimensional (2D) gadolinium tungstate nanoflakes (GW Nfs) are synthesized by a coprecipitation method and represent novel architectures for efficient catalysis, which could be used in electrochemical sensing and photocatalytic degradation of the postharvest fungicide carbendazim (CBZ). The physicochemical properties of GW Nfs were studied by using XRD, Raman, TEM, EDX, and XPS, which show the formation of GW as a nanoflake-like structure with a well crystallized nature.

Ethylcellulose assisted exfoliation of graphite by the ultrasound emulsification: An application in electrochemical acebutolol sensor.

This work reports the sonochemical exfoliation of graphite (bath sonication with the frequency of 37/80 kHz and power of 60 W) and its electrocatalytic properties to the β-blocker drug.

Herein, EC act as an emulsifier which aids to the exfoliation and also stabilizing the exfoliated graphite.
