Enhanced resistance to nanoparticle toxicity is conferred by overproduction of extracellular polymeric substances
TL;DR: Transmission electron microscopy (TEM) observations showed that EPS traps the nanoparticles outside the cells and reduces the exposed surface area of cells to incoming nanoparticles by inducing cell aggregation, which is likely effective mechanisms for reducing nanoparticle toxicity in the natural environment.

Biosynthesis and Characterization of Copper Nanoparticles Using Shewanella oneidensis: Application for Click Chemistry.
Richard L. Kimber,Edward A. Lewis,Fabio Parmeggiani,Kurt F. Smith,Heath Bagshaw,Toby Starborg,Nimisha Joshi,Adriana I. Figueroa,Gerrit van der Laan,Giannantonio Cibin,Diego Gianolio,Sarah J. Haigh,Richard A. D. Pattrick,Nicholas J. Turner,Jonathan R. Lloyd +14 more
TL;DR: A novel, simple, green biosynthesis method for producing efficient copper nanoparticle catalysts using the metal-reducing bacterium, Shewanella oneidensis, which is not dependent on the Mtr pathway commonly used to reduce other high oxidation state metals in this bacterium is demonstrated.

A pH-based biosensor for detection of arsenic in drinking water
TL;DR: An improved formulation allowing sensitive and accurate detection of less than 10 ppb arsenate with static overnight incubation is presented, and a cheap and simple high-throughput system for simultaneous monitoring of pH in multiple assays over time is described.

Microbial Reduction of Natural Fe(III) Minerals; Toward the Sustainable Production of Functional Magnetic Nanoparticles
Nimisha Joshi,Jan Filip,Victoria S. Coker,Jhuma Sadhukhan,Ivo Safarik,Heath Bagshaw,Jonathan R. Lloyd +6 more
TL;DR: In this article, the authors show that naturally abundant Fe(III) minerals are appropriate raw materials for the production of magnetic Fe(II)-bearing nanoparticles by the subsurface bacterium Geobacter sulfurreducens, and these bionanomaterials have the potential for remediation applications.

Life Cycle Assessment of Sustainable Raw Material Acquisition for Functional Magnetite Bionanoparticle Production
TL;DR: The potential adverse environmental impacts of MNP production via the biosynthesis system can be reduced by minimising sodium hydroxide and substituting ferric sulphate for ferric chloride, and considerable environmental benefits were exhibited in case (iv), where Fe(III) ions were sourced from metal-containing wastewaters and reduced to MNPs by electrons harvested from organic substrates.
