Porphyrins-as Active Materials in the Design of Sensors. An Overview

Abstract

This overview described the utilization of porphyrins as active compound in the design of different types of sensors. The modified electrodes with porphyrins showed a new approach in sensing of different compounds such as biogenic amines, vitamins, toxic and polyphenolic compounds, biomarkers. The porphyrins had many applications due to their large surface area, redox mediators, regular porosity and tunable structures, making them suitable for detecting small molecules. Different electrochemical and optical sensors were designed and applied successfully for clinical, food, and environmental analysis.
