Background: Inexpensive and disposable microfluidic sensing equipment is in strong demand which can detect biomarkers of diseases found in urine or blood. From recent studies, it has been found that multifilament threads can be used for producing low-cost microfluidic devices hence these multifilament threads act as an inexpensive alternative. Thread has various advantages to make it appropriate to be used in micro Read More

In this study, an electrochemical biosensor for the indirect detection of Adenosine triphosphate (ATP) was developed, which was based on the immobilization of the multiwalled carbon nanotubes (MWCNTs) decorated with pyrazole-capped selenium nanoparticles (TRPIDC-CH3 SeNPs) and dual enzyme reaction (hexokinase and glucose oxidase) onto the surface of a bare glassy carbon electrode (GCE) as a working electrod Read More

Background: In recent years, graphene oxide (GO) and its nanocomposites have shown effective performance in wastewater treatment. Moreover, graphene aerogels (GAs) have excellent properties, such as high surface area, high porosity, low density, high electrical conductivity, and good mechanical properties, due to the combination of three-dimensional porous structures and excellent properties of graphene. Methods: I Read More

Background: Inclusion of multiwall-carbon nanotubes (MWCNTs) as ion-to-electron transducers within the ionophore-doped PVC membrane has a great impact on the stability and robustness of the produced sensor performance compared to conventional liquid-based ISEs. Objective: Solid-contact ion selective electrodes (SC-ISEs) were fabricated and optimized for the assay of sulfacetamide sodium in both ophthalmic eye Read More

Background: The spectrophotometric detection of glucose usually requires the use of glucose oxidase (GOD) and horseradish peroxidase (HRP). These natural enzymes have specificity and can react with substrates efficiently and quickly, but their performance is easily influenced by external factors, such as humidity, temperature, and solution pH. In this study, no enzyme method was developed for the detection of glucose. O Read More

In the present investigation, an electrochemical sensing approach based on the electropolymerization modulation of brilliant green on a glassy carbon electrode has been introduced for rapid and sensitive identification of serotonin (SE) and epinephrine (EP) by cyclic and differential pulse voltammetric procedures. Under adequate circumstances, the analytical variable like the pH of the supporting solution, was maintained Read More

Background: For many years, seawater desalination technique has been operational to deal with water scarcity. In Boujdour region, located near the Atlantic Ocean southwest of Morocco, most water drinking is produced by a reverse osmosis seawater desalination plant. The permeate conductivity prediction is used to evaluate the performance of desalination plants. Objective: The present paper focuses on the modelin Read More
