Molybdenum disulfide-producing bacteria could be the future of bioelectronics

Written by Katie Gordon

Molybdenum disulfide

The metal-breathing bacterium Shewanella oneidensis produces molybdenum disulfide, which could be utilized for enhancing electronics, electrochemical energy storage and drug-delivery devices. In a study recently published in Biointerphases, researchers from Rensselaer Polytechnic Institute (NY, USA) investigated the production of a specific material from S. oneidensis. During anaerobic respiration, the bacterium “breathes” in metal and sulfur compounds and produces molybdenum disulfide, a material that researchers believe could be used to enhance bioelectronic devices as it can easily transfer electrons, similar to graphene. “This has some serious potential if we can understand this process and control aspects of how the bacteria are...
