Organic mixed ionic and electronic conductors (OMIECs) provide a versatile platform for establishing electrical communication with biological systems. In this talk, I will introduce this emerging class of materials for bioelectronic interfacing and discuss how their unique multifunctionality can be leveraged to develop next-generation optoelectronic devices operating at aqueous electrolyte interfaces. I will demonstrate how n-type OMIECs can be tailored to enable favorable interactions with catalytic enzymes and lipid bilayers, enabling the development of advanced biosensors. Building on this, I will present the aqueous-gated photoelectrochemical transistor (OPECT), a device based on these materials that can respond to both light and electrical stimuli and retain the generated information. By tuning the water uptake in the film and exploiting its strong near-infrared absorption, we create a water-compatible device that mimics the function of biological photoreceptors. Together, these developments highlight the potential of OMIECs to build new classes of adaptive, multifunctional bioelectronic sensors.
