Synthesis and characterization of bipyridine cobalt(ii) complex modified graphite screen printed electrode: an electrochemical sensor for simultaneous detection of acetaminophen and naproxen

Abstract

The new Co(ii) compound [Co(5,5′-dmbpy)2(NCS)2] (a1) was prepared by reacting Co(NO3)2·6H2O, 5,5′-dimethyl-2,2′-bipyridine ligand, and Na(SCN).

Screen-Printed Voltammetric Sensors—Tools for Environmental Water Monitoring of Painkillers

“…The naproxen drug should be given with precaution to elderly patients and patients with hemophilia, gastrointestinal bleeding, and platelet coagulation dysfunction. [ 92 ]. Ketoprofen is an arylpropionic acid derivative with anti-inflammatory, antipyretic, and analgesic properties [ 93 ].…”

“…There are no studies on voltammetric procedures to determine acetylsalicylic acid and naproxen in water samples in the literature. However, there are single procedures for determining AS [ 89 , 90 , 114 ] and NP [ 92 , 115 ] on screen-printed electrodes in pharmaceuticals and/or human physiological fluids. There are no attempts to use screen-printed sensors to analyze ketoprofen in any type of sample.…”

Metal Nanoparticles and Carbon-Based Nanomaterials for Improved Performances of Electrochemical (Bio)Sensors with Biomedical Applications

“…The screen-printed electrochemical sensing platforms have been applied for sensing and monitoring of a wide range of target analytes in many fields, such as food and drinks, environmental analysis, pathogens, cancer biomarkers and other relevant biomolecules, pharmaceutical analysis and biological analysis, performed in the traditional laboratories and also in-to-the-field (in-situ detection) [ 43 , 119 , 120 , 121 , 205 , 206 , 208 , 209 , 210 , 211 , 212 , 213 ]. In the case of the biosensors’ elaboration, the SPEs have been modified also with biological elements such as enzymes, antibodies and nucleic acids by applying various methods of immobilization (casting, physical adsorption, electrochemical coating or inclusion into the ink) [ 5 , 206 , 210 ].…”

“…Some different SPEs modified with Gd 2 O 3 NPs (size 23 nm, obtained via thermal precursor decomposition), La 3+ /Co 3 O 4 nanocubes and Fe 3 O 4 @cellulose nanocrystal/Cu nanocomposite and graphene have been developed for the determination of two antidepressant drugs (venlafaxine and sertraline) [ 121 , 287 , 288 ]. Various nanomaterials used for SPEs modification have been also employed for cysteine and acetaminophen analysis with considerable performances [ 119 , 213 ].…”

Application of a Screen-Printed Sensor Modified with Carbon Nanofibers for the Voltammetric Analysis of an Anticancer Disubstituted Fused Triazinone

“…Screen-printing techniques offer simple means of possible mass production of disposable, stable, and low-cost screen-printed electrodes to be used in on-site analyses [ 15 , 16 ]. Screen-printed electrodes are often employed in analytical applications due to their specific characteristics, including small dimensions and determination limits, quick response duration, reproducibility, ability to operate at room temperature, and low background current [ 5 , 17 , 18 ]. Additional advantages of screen-printed electrodes are diversification of the selection of electrode materials, portability, reliability for detecting different substances, and an ease of surface modification for various uses [ 19 ].…”
