The rapidly developing research field of organic analogue sensors aims to replace traditional semiconductors with naturally occurring materials. Photosensors, or photodetectors, change their electrical properties in response to the light levels they are exposed to. Organic photosensors can be functionalised to respond to specific wavelengths, from ultra-violet to red light. Performing cyclic voltammetry on fungal mycelium and fruiting bodies under different lighting conditions shows no appreciable response to changes in lighting condition. However, functionalising the specimen using PEDOT:PSS yields in a photosensor that produces large, instantaneous current spikes when the light conditions change. Future works would look at interfacing this organic photosensor with an appropriate digital back-end for interpreting and processing the response.

真菌光电传感器

快速发展的有机模拟传感器研究领域旨在用天然材料取代传统半导体。光电传感器或光电探测器会根据它们所暴露的光线水平改变它们的电特性。有机光传感器可以功能化以响应特定波长，从紫外线到红光。在不同光照条件下对真菌菌丝体和子实体进行循环伏安法显示对光照条件的变化没有明显的反应。然而，使用 PEDOT:PSS 对样品进行功能化会产生光传感器，当光照条件发生变化时，该光传感器会产生大的瞬时电流尖峰。未来的工作将着眼于将这种有机光传感器与适当的数字后端连接起来，以解释和处理响应。
