“…63 Ipak, razvoj CPE u sve je većem fokusu znanstvene zajednice, s obzirom na broj od preko 40000 publiciranih znanstvenih članka (s terminom CPE) u posljednjih dvadesetak godina (slika 4). CPE se rabe u kulometriji, voltametriji, amperometriji i potenciometriji, i pronalaze vrlo široku primjenu, u prvom redu, za određivanje djelatnih spojeva u raznim farmaceutskim pripravcima, o čemu će biti govora u nastavku ovog rada, zatim u veterini, 59,[64][65][66] u detekciji umjetnih bojila u prehrambenim proizvodima, 67 teških metala u vodi i urinu, 68 dopamina, 69,70 nesteroidnih protupalnih lijekova u otpadnim vodama 71,72 upotrebljavaju se i kao biosenzori glukoze, 40,41,[73][74][75] za mjerenje tumorskih markera [76][77][78] i kolesterola u krvi 79,80 i dr.…”

The development of carbon paste electrodes in the 1970s generated considerable interest in the scientific community, because they offered several advantages over conventional membrane electrodes. At the beginning of the new millennium, the use of carbon nanomaterials as a new trend in their development gave additional impetus. After CPEs were successfully developed for potentiometric determination of more than 70 chemical elements, these electrodes gained additional interest for pharmaceutical and medical applications. This paper reviews the scientific literature of the last decade related to the development of CPEs for the quantitative determination of active pharmaceutical ingredients and their application in real samples.

Veterinary drug residues in food have emerged as an urgent threat to consumer safety. Herein, we present the first square wave voltammetric method for the trace-level detection of cinnarizine residues, a recently used antischistosomal drug, in bovine food samples. The method depends on the electrochemical oxidation after modification of the carbon paste sensor with recycled Al2O3-NPs functionalized multi-walled carbon nanoparticles. The produced sensor (Al2O3-NPs/ MWCNTs/CPE) was characterized using the transmission electron microscope, scanning electron microscope, Fourier-transform infrared spectroscopy, energy-dispersive spectrometer, and X-ray diffractometer that confirm the successful incorporation of the Al2O3-NPs/MWCNTs composite into the modified electrode. As expected, the active surface area and electron transfer processes were accelerated by the modification, which was evidenced by cyclic voltammetry, chronoamperometric studies, scan rate studies, and electrochemical impedance spectroscopy. Compared to previous techniques, this facile sensor demonstrated enhancements across critical analytical criteria including the detection limit of 0.17 nM, linear response across 5–100 nM (r2 = 0.998), accuracy ranging from 96.5 to 103.2%, precision below 0.81% relative standard deviation, reproducibility within 0.36% range, 20 s response time and applicability in spiked food matrices. In addition, five different greenness and whiteness tools quantified exceptional environmental friendliness, economic feasibility and waste reduction of 63%–93%, reaffirming alignment with sustainability paradigms. These advantages support practical adoption in quality control especially laboratories lacking expensive instrumentation. Overall, the ingenious sensor reconciles nanotechnology innovation with the circular economy ethos to tackle an urgent food safety challenge, guided holistically by sustainability metrics.
