Microbial Nanowires

Some microorganisms, such as Geobacter and Shewanella, have the natural ability to produce microbial nanowires, which are thin, conductive protein threads. These nanowires are composed of a protein called PilA, which forms elongated filaments that efficiently facilitate the transport of electrons over considerable distances.

These remarkable microbial nanowires are believed to play a vital role in facilitating electron transfer processes in particular environments, such as sediments and soils. In these settings, these nanowires act as efficient "cables," enabling the transfer of electrons from microorganisms to other cells or minerals within the environment.

Recent years have witnessed a growing interest in microbial nanowires due to their promising applications in the fields of bioelectronics and biotechnology. For instance, they can be integrated into microbial fuel cells, innovative devices that harness electricity from the metabolic activities of microorganisms. Additionally, these nanowires can serve as conductive frameworks for the cultivation of other microorganisms, which can be harnessed to produce valuable products like biofuels and pharmaceuticals.

Ongoing research endeavors are dedicated to a deeper understanding of microbial nanowire properties and their diverse applications. These efforts also aim to develop novel techniques for their production and manipulation. As this research progresses, microbial nanowires hold significant potential to become integral components in the emerging domains of bioelectronics and biotechnology.
