Revisiting Some Recently Developed Conducting Polymer@Metal Oxide Nanostructures for Electrochemical Sensing of Vital Biomolecules: A Review

Electrochemical Probing the Site Reactivity in Iron Single-Atom Catalysts for Electrocatalytic Nitrate Reduction to Ammonia

“…The proposed electrochemical probing technique to characterize the intrinsic activity of Fe SACs was conducted as depicted in Figure . Previously, molecular probe techniques have been widely reported in the field of analytical chemistry. − In this work, SCN – was selected as the molecular probe to detect the intrinsic site activity as SCN – can specifically adsorb at the Fe sites in Fe-NC catalyst according to previously reported . While the irreversibility of SCN – adsorption at the Fe site has not been definitively demonstrated thus far, several studies have indicated that SCN – is expected to coordinate axially to M-NC centers, inhibiting their reactivity. ,− On the other hand, compared with other poisoning ions (halogen ions, CO, H 2 S, et al), SCN – has stronger poisoning ability to Fe sites and safer .…”

Titania (TiO2)/silica (SiO2) nanospheres or NSs amalgamated on a pencil graphite electrode to sensel-ascorbic acid electrochemically and augmented NSs for antimicrobial behaviour

“…Moreover, these materials are low cost, easily synthesizable and also utilized in different sensing applications. [32][33][34] As evident, TiO 2 and SiO 2 materials composited with polymers, metals, metal oxides and rGO in binary and ternary forms have been reported for ascorbic acid detection. 9,[35][36][37] Such binary metal oxide (TiO 2 /SiO 2 ) based materials have already been reported in different forms including nanocomposites, nanotubes and nanofilms.…”

Enzymatic Electrochemical Biosensor from Eu‐Doped SnO2 Embedded in MXene for High Performance Sensing Lactate

“…Blood lactate levels are now applied as an indicator of health and clinical condition [4] . In recent years, electrochemical sensors have attracted more and more attention due to their advantages of simple operation, fast response speed, low detection limit, high sensitivity, easy miniaturization, and relatively low cost [5–9] . Hence, developing high‐sensitivity lactate sensors is crucial to clinical diagnosis, intensive care, and sports medicine [10] …”

“…[4] In recent years, electrochemical sensors have attracted more and more attention due to their advantages of simple operation, fast response speed, low detection limit, high sensitivity, easy miniaturization, and relatively low cost. [5][6][7][8][9] Hence, developing high-sensitivity lactate sensors is crucial to clinical diagnosis, intensive care, and sports medicine. [10] In the past ten years, semiconductor metal oxides, as an excellent sensing substrate, have been widely used in automobile emission monitoring, environmental monitoring, and food safety inspection due to their low cost of production, convenient operation, high sensitivity and ability to determine various gases.…”
