“…It can be seen that CAP can be detected at 0.64 mg/mL (SD = 0.20, R = 0.9992 ( n = 5)). The calculated correlation coefficients are quite similar to those obtained earlier using various approaches for determining CAP like chromatography, − fluorometry, − UV–visible spectroscopy, , chemiluminescence, voltammetry, − potentiometry, − and conductometry − methods. Using the proposed methods, CAP was determined successfully over a concentration range from 0.83 to 13.04 mg/mL (Figure ).…”

“…Captopril (CAP), also known chemically as [2S]-N-[3-mercapto-2-methylpropionyl)-L-proline, is a broadly utilized drug for the treatment of high blood pressure, diabetic nephropathy, congestive heart seizure, and the preservation of kidney damage. , In order to investigate the presence of CAP in pharmaceuticals, numerous analytical procedures have been postulated. CAP was determined using chromatography, − fluorometry, − UV–visible spectroscopy, , chemiluminescence, and voltammetric techniques. − Although these analytical strategies are highly sensitive and accurate, they are costly, time-consuming, and require complex procedures for sample preparation and analysis protocols.…”

“…Under the optimized conditions, the linear calibration plots from 1 to 5 × 10 4 nM (two segments, 1-150 nM and 0.15-50.0 μM) and the detection limit is calculated to be 0.4 AnM (S / N = 3) . Finally, the suggested sensors show a stable and reliable CP response in CP pharmaceutical tablets and urine samples [21]. Chlorpromazine is used as a homogeneous electrocatalyst in captopril oxidation.…”

Captopril is the most commonly prescribed ACE-Inhibitor class of drugs because it is easily accessible and affordable. Therefore, to ensure drug quality, captopril levels were determined. This review article aims to provide an overview of the various analytical techniques that have been carried out in selecting the groups of captopril in both pharmaceutical dosage forms and biological matrices. Some of these analytical methods include the UV-Visible spectrophotometric method, high-performance liquid chromatography (HPLC), voltammetry, and flow injection. The data collection process in this review article is to collect research journals through trusted sites in the last ten years (2011-2021) with the search keywords "Determination of Captopril," "Analysis of Captopril on Pharmaceutical Preparations," and Analysis of Captopril on Biological Matrices." From the data that has been collected, the voltammetric method is the most widely used analytical technique in determining captopril for both pharmaceutical preparations and biological matrices in the last ten years.

“…This causes slower reaction kinetics, ultimately leading to decreased sensitivity. 34,35 To further understand the kinetics of electrochemical phosphate sensing, a CV was run in the presence of 100 μM phosphate at different scan rates from 10 to 200 mV/s (Figure 5a). Both the anodic and cathodic peaks (magnitude) in CV show an increasing trend with respect to scan rate.…”

The fundamental understanding of the electrochemical transport of ions at the interface of nanoscale materials and its immediate environment lays the foundation to build electrochemical sensors for a wide variety of chemical, biological, and environmental problems. Therefore, enabling an efficient electron transfer from the environment to an atomically thin, two-dimensional material such as graphene and vice versa provides a route to building graphene-based electrochemical sensors. Although many graphene-based electrochemical sensors have been reported in recent years, there have been limitations in designing and manufacturing them to monitor phosphate ions in the environment. This limitation primarily arises from the lack of high-performance printable graphene nanoinks (in terms of their combined electrical conductivity and electrochemical charge transfer properties) as well as complexity in the detection of phosphate ions. Herein, we report the manufacturing of a high-quality graphene nanoink and its use for the first time in fabricating stable and reliable printed phosphate ion electrochemical sensors using a microplotter. These sensors demonstrate a sensitivity of 0.3223 ± 0.025 μA μM–1 cm–2, with a limit of detection (LOD) of 2.2 μM and linear sensing range of 1–600 μM. Moreover, they exhibit high selectivity toward phosphates when tested in the presence of NO3 –, CO3 –, Cl–, and SO4 2– interfering ions, affirming their reliability as a sensing platform. Phosphate electrochemical sensing using the proposed printed graphene sensors will pave the way for future development of point-of-care and continuous phosphate monitoring in environmental sensing.
