Among organic thin film transistors (OTFTs), Organic Electrochemical Transistors (OECTs) have been extensively used for cell monitoring while Electrolyte-Gated Organic Field-Effect Transistors (EGOFETs) have never been described for that kind of application. However, EGOFETs are well adapted for this use because, as well as OECTs, they can operate directly in aqueous solutions such as cells culture media, but they offer much a higher on/off ratio which could lead to better sensitivity. As a proof of concept, we propose herein to monitor the photosynthetic activity of a cyanobacterium (Anabaena flos-aquae) contained within an EGOFET's electrolyte.

在有机薄膜晶体管（OTFT）中，有机电化学晶体管（OECT）已广泛用于电池监控，而电解质门控有机场效应晶体管（EGOFET）从未针对此类应用进行过描述。但是，EGOFET与OECT一样非常适合这种用途，因为它们可以直接在水溶液（例如细胞培养基）中运行，但是它们提供了更高的开/关比，这可能导致更高的灵敏度。作为概念的证明，我们在此建议监视EGOFET电解质中所包含的蓝细菌（鱼腥藻）的光合作用活性。
