Project description
Bacteria-inspired biocompatible and biodegradable electronics
Microorganisms and mitochondria use electron transport chains, membrane-bound protein complexes, to transfer electrons from donors to receptors and produce the energy needed for metabolic functions. Until recently, biological electron transport was thought to occur over nanometre distances, but the discovery of what are called cable bacteria that can guide currents over centimetre-long distances is turning that idea upside down. The partners of the EU-funded PRINGLE project found that protein fibres embedded in the cell envelope of these bacteria have an electrical conductivity exceeding that of any known biological material by orders of magnitude. The project will pursue this line of research to find tailor-made protein structures and a new generation of biocompatible and biodegradable electronic devices.

Recent studies by PRINGLE consortium members reveal that these protein fibers possess extraordinary electrical properties, including an electrical conductivity that exceeds that of any known biological material by orders of magnitude. The ambition of PRINGLE is to unlock the vast technological potential of this newly discovered biomaterial. To this end, we propose to utilize custom-crafted protein structures as elementary active and passive components in a new generation of biocompatible and biodegradable electronic devices. The resulting long-term technological vision is to establish a radically new type of electronics (PROTEONICS) that is entirely bio-based and CO2 neutral, and in which protein components can provide different all types of electronic functionality. PRINGLE will provide the fundamental and technological basis for PROTEONICS by (1) developing fabrication and patterning technologies for proteonic materials and nanostructures, (2) tuning the electronic properties of these proteonic materials in a fit-for-purpose manner, and (3) integrating proteonic materials as functional components into all-protein electronic devices. As such, PRINGLE-based technology could provide a significant breakthrough towards next generation electronics applications in a circular economy, opening entirely new avenues for interfacing biological systems with electronics and allowing completely new sustainable production and recycling pathways for electronic components.
