“…As a result, β-blocker medications are increasingly being used to treat hypertension. Atenolol (ATN) is a β-blocker drug that is widely used to regulate blood pressure by blocking β 1 adrenergic receptors [ [1] , [2] , [3] ]. In addition, the use of this drug by athletes is considered doping because of its sedative properties [ 4 , 5 ].…”

“…Due to its excellent biocompatibility with edgy functionalities, GQDs were also reported to adsorb the enzyme laccase on glassy carbon electrode for the determination of a neurotransmitter epinephrine. By forming covalent bonds, glutaraldehyde is used as a crosslinker to maintain a stable laccase layer on GQDs [19], where laccase is a green multi-copper oxidase and was proved to catalyze the electrochemical oxidation of atenolol [20]. Furthermore, the π-π network of GQDs also provides possibilities for the electrostatic adsorption of beta-blockers.…”

Beta-blockers are generally prescribed for cardiovascular treatment and sometimes as sedative drugs for professionals such as musicians and athletes, which can cause serious side and adverse effects when the dosage is high. Additionally, beta-blockers are maintained as prohibited drugs for athletes by World Anti-Doping Agency (WADA). It is urgent to develop quick, simple and affordable analytical tools for beta-blockers. Electrochemical sensors have been favored by researchers for their simplicity, portability and quick detection. Therefore, this review discusses the most common voltammetric sensors for beta-blockers, along with two important features for effective determination: sensitivity and selectivity, which are realized by chemically modified electrodes.

The starting point of this study was to propose a simple and rapid electrochemical approach for quantitative analysis of heavy metal ions in natural mineral water samples. For this purpose, it was aimed to quantitatively determine Cd (II) and Pb (II) ions in gaseous mineral waters by square wave anodic stripping voltammetry (SWASV) by modi cation of pencil graphite electrode (PGE) with graphene oxide (GO) and deposition of auric acid solution. A three-step modi cation process was implemented to the PGE surface, including graphene oxide coating (GO/PGE), GO reduction (ERGO/PGE), and gold coating (Au-ERGO/PGE). The morphologies and electrochemical properties of the developed electrode were checked with scanning electron microscopy (SEM), cyclic voltammetry (CV), and SWASV. The results show the synergistic effect of graphene oxide and auric acid-activated surface and good electrical conductivity leading to the deposition of Cd (II) and Pb (II) on the electrode surface. Under optimum conditions, a linear behavior was obtained between currents and Cd (II) and Pb (II) concentrations in the range of 0.6-1.6 µM and 0.4-1.6 µM. Detection limits were calculated as 0.36 µM and 0.24 µM for Cd (II) and Pb (II), respectively. Finally, the improved electrode was applied for the detection of Cd (II) and Pb (II) in gaseous natural mineral water samples with high recovery rates. This study revealed that Au-ERGO/PGE modi cation could be an alternative route in practical applications of electrochemical detection of heavy metal ions.2.4.
