“…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.…”

“…100 Elektroda NiMn 2 O 4 na bazi paste od ugljikova materijala primijenjena je pri osjetljivom određivanju sarkozina, dobro poznatog biomarkera raka prostate. Izvanredna osjetljivost i visoka selektivnost metode u rasponu koncentracija 0,01 -5,00 μmol l −1 i s relativnim standardnim odstupanjem od 3,49 % omogućuje primjenu senzora u mjerenju koncentracije sarkozina u realnim uzorcima, 78 a kao takva mogla bi postati standard u određivanju navedenog.…”

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.

“…To date, traditional electrodes, such as glassy carbon electrodes, [29][30][31] carbon paste electrodes, [32][33][34] and screenprinted electrodes, are made up of rigid and solid substrates, which makes them difficult to use for the wearable sensing of glucose on human skin. To resolve the above problems, a new method for the batch fabrication of flexible electrodes, which is easy to use, low-cost, and efficient, has been developed by the laser inducing of a flexible polyimide (PI) film to generate porous graphene, i.e., laser-induced graphene (LIG), with specific patterns under controllable laser power.…”

In this study, a flexible and wearable chemiresistive biosensor (FWCB) is developed for the real‐time analysis of glucose in sweat on the human skin surface based on a novel detection strategy of p‐type reduced graphene oxide (rGO) sensing film, which met the requirements of rapid, nondestructive testing. The proposed FWCB is fabricated in the form of interdigital electrodes (IEs) made of laser‐induced graphene (LIG) synthesized by the laser inducing of a polyimide (PI) film. Additionally, a semiconducting rGO sensing film modified on the surface of IEs is synthesized by thermal reduction of graphene oxide (GO), which is functionalized with glucose oxidase (GOx) by chemical cross‐linking to obtain GOx/FWCB. Moreover, the key parameters for FWCB fabrication are optimized, and the sensing strategy of the proposed GOx/FWCB is also investigated. The results show that the proposed GOx/FWCB can be used for the detection of glucose in the range of 0.01–3.0 mM with satisfactory selectivity, and the limit of detection (LOD) is calculated to be as low as 0.8 µM (S/N = 3). These dramatic advantages endow the proposed FWCB with broad application prospects in the field of portable, wearable, and real‐time detection of glucose in human sweat for health monitoring.

In the evolving field of electrocatalysis, thermal treatment of nano‐electrocatalysts has become an essential strategy for performance enhancement. This review systematically investigates the impact of various thermal treatments on the catalytic potential of nano‐electrocatalysts. The focus encompasses an in‐depth analysis of the changes induced in structural, morphological, and compositional properties, as well as alterations in electro‐active surface area, surface chemistry, and crystal defects. By providing a comprehensive comparison of commonly used thermal techniques, such as annealing, calcination, sintering, pyrolysis, hydrothermal, and solvothermal methods, this review serves as a scientific guide for selecting the right thermal technique and favorable temperature to tailor the nano‐electrocatalysts for optimal electrocatalysis. The resultant modifications in catalytic activity are explored across key electrochemical reactions such as electrochemical (bio)sensing, catalytic degradation, oxygen reduction reaction, hydrogen evolution reaction, overall water splitting, fuel cells, and carbon dioxide reduction reaction. Through a detailed examination of the underlying mechanisms and synergistic effects, this review contributes to a fundamental understanding of the role of thermal treatments in enhancing electrocatalytic properties. The insights provided offer a roadmap for future research aimed at optimizing the electrocatalytic performance of nanomaterials, fostering the development of next‐generation sensors and energy conversion technologies.
