High levels of metallic ions, particularly heavy metals, can cause serious damage not only to public health but to the whole ecosystem. Therefore, rapid and precise detection and monitoring of heavy metals have become vital. The detection of heavy metals in water using conventional monitoring approaches based on physicochemical and analytical procedures, e.g., inductively coupled plasma combined with atomic ab Read More

Background: Worldwide, the prescriptions for asthma drugs are on the rise. However, antiasthma drugs have side effects and can lead to fatal death at higher doses. Quite often, these drugs are abused as growth promoters in poultry/livestock as well as by athletes to enhance their performance. Consequently, it is vital to design uncomplicated, portable, rapid and highly sensitive means of detecting these anti-asthm Read More

In recent decades, increased demand for food has been caused by a rapid rise in the human population, which triggers agricultural intensification. To resist undesired pests from infecting crops, farmers widely utilize pesticides to improve agricultural production during the pre-harvest period. Despite the fact that pesticides cause a number of health risks, there is insufficient monitoring of these toxins. Therefore, it is important Read More

Background: Sertraline (ST) hydrochloride is an anti-depressant of the selective serotonin reuptake inhibitor (SSRI) class. Potentiometric sensors are an appealing route for detecting drugs due to some advantages in terms of sensitivity, feasibility, selectivity, fast response, tolerance to turbidity and colour of solutions, and cost-effectiveness. Methods: A mixture of polyvinyl chloride powder (PVC) with o-nitrophenyl octyl ether and Read More

Background: In the current research, a green, fast and cheap extraction method based on deep eutectic solvent was developed for the preconcentration of phenylalanine. Then, high performance liquid chromatography (HPLC) as a sensitive and accurate technique was used to determine amounts of preconcentrated phenylalanine. Objective: The combination of the HPLC technique and extraction procedure usin Read More
