Some bacteria that are adapted to specific geochemical or biochemical environments can create interesting and novel materials. Researchers at the Rensselaer Polytechnic Institute synthesised molybdenum disulfide nanomaterials at the site of S. oneidensis biofilms grown in the presence of molybdenum trioxide and sodium thiosulfate. Analysis revealed the presence of molybdenum disulfide nanoparticle aggregates 50–300 nm in diameter with both hexagonal and rhombohedral polytypes. The use of S. oneidensis offers the advantage of significantly reduced heat and chemical solvent input compared to conventional methods of synthesizing molybdenum disulfide nanoparticles. The process can be used for the generation of ‘living sensors’…read more. Open Access TECHNICAL ARTICLEÂ
