Amperometric biosensors: Harnessing photosynthetic reaction centers for herbicide detection
Source abstract
Abstract
Amperometric biosensing, exemplified by the popular glucose biosensor, is a well-established method for transducing analyte-receptor binding events into accessible electronic outputs. Herbicide biosensors leverage natural photosynthetic reaction centers to measure directly at the site of herbicide action. Recent advancements at the biohybrid interface between photosynthetic complexes and electrodes have led to substantial improvements in transduction efficiency and photoelectrode stability that are essential for herbicide biosensing. This review focuses on herbicide biosensors employing isolated photosynthetic reaction centers, thylakoids, and whole cells as bioreceptors which are coupled to electrochemical transduction platforms. We critically evaluate biosensor performance metrics of sensitivity, specificity, stability, ease of use, and affordability, all of which must be embodied in one biosensor device for practical implementation.
