Abstract
The development of sustainable materials is becoming increasingly important for the next generation of bioelectronic technologies. Organic mixed ionic–electronic conductors (OMIECs) provide a unique platform for interfacing electronics with biological systems, yet most state-of-the-art materials still rely on synthetic polyelectrolytes. Our research explores an alternative strategy by integrating renewable biological macromolecules with electrically conducting polymers to create sustainable and biocompatible mixed conductors.
Naturally derived materials, including DNA recovered from marine residuals1,2, polysaccharides from blue-green algae3, nanocellulose from plants4, and lignosulfonates5 from the wood industry as well as emerging degradable polymers derived from renewable building blocks are employed as functional counterions for conducting polymers such as PEDOT and polypyrrole. Beyond stabilizing the conducting polymer, these bio-derived components actively influence ionic transport, electrochemical properties, and device operation.
This presentation will highlight the design and implementation of these conducting polymer biocomposites in organic electrochemical transistors (OECTs) and biosensing platforms, demonstrating how renewable materials can simultaneously enhance functionality and sustainability. The results illustrate that bio-derived polymers are not merely passive structural components but active contributors to mixed ionic–electronic transport and signal transduction.
By combining green materials chemistry with organic bioelectronics, this work presents a pathway toward environmentally responsible electronic technologies for healthcare, biosensing, and future soft biointerfaces.
