Front Cover: Versatile Metalloporphyrin‐Based Electrochemical Sensing Applications: From Small Gasotransmitters to Macromolecules (Eur. J. Inorg. Chem. 17/2023)

Abstract

The Front Cover shows an engaging platform for electrochemical sensor development: Metalloporphyrins. Although the last years have been times of numerous technological transitions, porphyrins have been and currently are critical building blocks in the development of micro-/nanosensors. In recent years, not only have small molecules been detected and quantified, but it is now also possible to measure relevant macromolecules with high precision in intricate samples. This work presents an up-to-date list of reports in which metalloporphyrins are used as electrochemical sensors. Most of them are developed with a blend of porphyrin rings and metals of the first transition series. Renewed efforts in the synthesis, improved electronics, and data analysis will lead to better performance and new applications of metalloporphyrin-based electrochemical sensors in the coming years.
