A novel sulfur-bridged metal–organic framework (MOF) [Co(TIC4R-I) 0.25 Cl 2 ]·3CH 3 OH (Co-TIC4R-I) based on thiacalix[4]arene derivatives was successfully obtained using a solvothermal method. Remarkably, adjacent TIC4R-I ligands were linked via Co(II) cations to form a three-dimensional (3D) microporous architecture. Subsequently, Co-TIC4R-I was modified on a glassy carbon electrode (Co-TIC4R-I/GCE) to produce an electrochemical sensor for the detection of heavy-metal ions (HMIs), namely, Cd2+, Pb2+, Cu2+, and Hg2+, in aqueous solutions. It was found that Co-TIC4R-I/GCE exhibited wide linear detection ranges of 0.10–17.00, 0.05–16.00, 0.05–10.00, and 0.80–15.00 μM for Cd2+, Pb2+, Cu2+, and Hg2+, respectively, in addition to low limit of detection (LOD) values of 0.017, 0.008, 0.016, and 0.007 μM. Moreover, the fabricated sensor employed for the simultaneous detection of these metals has achieved LOD values of 0.0067, 0.0027, 0.0064, and 0.0037 μM for Cd2+, Pb2+, Cu2+, and Hg2+, respectively. The sensor also exhibited satisfactory selectivity, reproducibility, and stability. Furthermore, the relative standard deviation (RSD) values of Cd2+, Pb2+, Cu2+, and Hg2+ were 3.29, 3.73, 3.11, and 1.97%, respectively. Moreover, the fabricated sensor could sensitively detect HMIs in various environmental samples. The high performance of the sensor was attributed to its sulfur adsorption sites and abundant phenyl rings. Overall, the sensor described herein provides an efficient method for the determination of extremely low concentrations of HMIs in aqueous samples.

“…When combined with a 4-aminoantipyrine–peroxidase system, the uricase test is one of the most effective enzymatic determinations of UA. Evaluating the UA concentrations in human bodily fluids is thus clinically beneficial and important for prevention of the previously described disorders or even other comparable disorders. − Furthermore, UA concentration monitoring in human bodily fluids is critical; different detection methods, which include enzyme detection, high-performance liquid chromatography (HPLC), UV detection, mass spectrometry, colorimetry, and electrochemical sensors, have been developed in response to earlier studies. , However, many of these procedures may necessitate elaborate pretreatments or take an excessive amount of time . Because of its unusual electrochemical activity, UA may be permanently oxidized into active ingredients in an aqueous solution.…”

Researchers are now aiming to develop multifunctional materials that are nontoxic, minimal in cost, and simple to produce and have superior efficiency for large-scale electrochemical sensor applications. Uric acid (UA) is a biomarker correlated with gout and kidney stones that has an adverse effect on the human body. Here, UA was measured using differential pulse voltammetry (DPV) and amperometric (i–t) techniques with a superactive Wolframite structure of CuWO4. CuWO4 was characterized using a variety of microscopic and spectroscopic methods. The data collected indicated that the electrode modified with CuWO4 provides a superior electrochemical oxidation peak current compared with the bare electrode. CuWO4 exhibits wide linear ranges, with a lower limit of detection obtained from DPV and i–t techniques. Furthermore, the CuWO4-modified sensor has been used to determine the concentration of UA in urine and bovine serum albumin samples. Moreover, the CuWO4-modified sensor has great stability and reproducibility.
