Versatile Metalloporphyrin‐Based Electrochemical Sensing Applications: From Small Gasotransmitters to Macromolecules

Abstract

AbstractAt the beginning of his youthful sixth decade, this work is dedicated to Prof. Dr. Fabio Doctorovich. He is distinctive in organometallic chemistry. During his successful career, he has been studying the reactivity and application of metalloporphyrins. Metalloporphyrins are organometallic complexes that exhibit, through synthetic modifications, the ability to tune their optical and electrochemical properties and their selectivity towards a particular molecule or ion. For this reason, they are systems extremely useful as electrochemical sensors to detect and quantify a wide variety of analytes with high selectivity, even in real samples such as food, water, biological fluids, or pharmaceutical compounds. This review presents an up‐to‐date list of reports in which metalloporphyrins are used as electrochemical sensors. In addition to compiling a comprehensive and up‐to‐date list of reported sensors that utilize metalloporphyrins, this work aims to provide an overview of currently available tools and techniques for the detection of various chemical species through similar approaches, which are constantly being developed.
