Abstract

Innovative design enhancements to microbial fuel cells (MFCs) are pivotal for improving their viability as renewable energy sources. This study introduces a dual approach to electrode modification, integrating polyaniline (PANI) and gold nanoparticles (AuNPs) on carbon felt (CF) anodes coupled with a unique cathode composed of DNA origami and chitosan. The synergistic effect of PANI and AuNPs significantly increases the hydrophilicity and conductivity of the anode, leading to a considerable surge in power density. Concurrently, the biocompatible DNA origami and chitosan-functionalized cathode facilitates efficient electron transfer without relying on conventional catalysts. Together, these modifications yield a 52.42% increase in the maximum power density, illustrating a scalable and economical path to potentiate MFCs. The findings present a promising avenue for advancing MFC technology, emphasizing the potential of nanomaterials in enhancing bio electrochemical systems. This succinct yet comprehensive strategy marks a step forward in the practical application of MFCs for sustainable energy production.
