“…Until recently, most research has focused on using microorganisms to produce nano-size metallic or semimetallic material that can serve either as a conductor, as the sensing component in electronic sensors, or for electrical energy storage. A diversity of microbes or enzymes extracted from microbial cells can produce nanoparticles from a wide range of metals, including gold, silver, palladium, and platinum ( 3 , 4 ). Sizes and shapes depend on the microorganisms and environmental conditions employed.…”

“…Sizes and shapes depend on the microorganisms and environmental conditions employed. Semiconductor materials such as metal sulfides, metal oxides, and elemental selenium can also be microbially produced either intracellularly or extracellularly ( 3 ). Remarkable in this regard is the formation of arsenic-sulfide nanotubes by Shewanella species from the reduction of As(V) to As(III), concomitant with the reduction of thiosulfate to sulfide ( 5 , 6 ).…”

The growing ubiquity of electronic devices is increasingly consuming substantial energy and rare resources for materials fabrication, as well as creating expansive volumes of toxic waste. This is not sustainable. Electronic biological materials (e-biologics) that are produced with microbes, or designed with microbial components as the guide for synthesis, are a potential green solution. Some e-biologics can be fabricated from renewable feedstocks with relatively low energy inputs, often while avoiding the harsh chemicals used for synthesizing more traditional electronic materials. Several are completely free of toxic components, can be readily recycled, and offer unique features not found in traditional electronic materials in terms of size, performance, and opportunities for diverse functionalization. An appropriate investment in the concerted multidisciplinary collaborative research required to identify and characterize e-biologics and to engineer materials and devices based on e-biologics could be rewarded with a new “green age” of sustainable electronic materials and devices.

“…An array of nanoparticle compositions are successfully synthesized by using whole cells or cellular components to catalyze and template the growth of particles. − Performed intracellularly, biogenic synthesis of nanoparticles yields biocompatible and functionalized nanoparticles in reliably “green” syntheses that could enable self-assembled cellular or molecular tags. − However, for intracellular synthesis of nanoparticles it is expected that enzymatic and nonenzymatic pathways represent competing mechanisms for particle formation. To pursue biogenic synthesis as a means of generating cellular or molecular tags in vivo, it becomes critical to identify pathways that enable control over the final product within a complex, competitive system.…”

Enzyme-Catalyzed in Situ Synthesis of Temporally and Spatially Distinct CdSe Quantum Dots in Biological Backgrounds

et al. 2019

The cellular machinery of metal metabolism is capable of making a wide range of inorganic nanoparticles and quantum dots. Individual enzymes from these metabolic pathways are being identified with metal reducing activity, and some have been isolated for in situ particle formation and labeling. We previously identified a glutathione reductase like metalloid reductase (GRLMR) from Pseudomonas moravenis stanleyae with a high affinity for the bioavailable selenium thiolate selenodiglutatione and exhibiting NADPH-dependent reduction of selenodiglutathione to Se(0), initiating the growth of pure selenium metal nanoparticles. In this study, we demonstrate that the GRLMR enzyme can further reduce selenium to a Se(2−) oxidative state, which is capable of nucleating with Cd(2+) to rapidly form CdSe quantum dots. We show that GRLMR can outcompete background sources of cellular selenium reduction (such as glutathione) and can control the kinetics of quantum dot formation in complex media. The resulting particles are of smaller diameter, with a distinguishingly shifted emission spectrum and superior full width at half-maximum. This study indicates that there is great potential for using GRLMR to study and design enzymes capable of controlled biosynthesis of nanoparticles and quantum dots, paving the way for cellularly assembled nanoparticle biosensors and reporters.

“…For this reason, studies related to the behavior of ENP and their applications have increased in recent years (Dasgupta, Ranjan, & Ramalingam, 2017;Salouti & Zonooz, 2017), which has generated concern, due to the possibility that these particles are being released into the atmosphere, oceans, groundwater, bodies of water, rivers, soil, or living organisms, from industrial effluents, domestic and other personal hygiene products (Goyal & Basniwal, 2017;León-Silva, Fernández-Luqueño, & López-Valdez, 2016;Terekhova et al, 2017). In this sense, ENP could be toxic due to their physicochemical properties, which are not included in toxicity standards (Goyal & Basniwal, 2017;Rasmussen et al, 2016).…”

Effect of engineered nanoparticles on soil biota: Do they improve the soil quality and crop production or jeopardize them?

et al. 2020

Nanoscience and nanotechnology have been shown to have the capacity to help study, manipulation,design, and synthesis of new nano-sized materials to manufacture new products with desirable features never seen before. The unique properties of materials at nanoscale opens an excellent possibility for nanotechnology to be used in soil environmental remediation, and water, and air decontamination. In crop management, nanomaterials are used to regulate the controlled release of nutrients, fertilizers, and pesticides. However, it is not only necessary to expose the positive effects by the application of the nanomaterials but also to demonstrate the impacts on soil and nontarget organisms (plants, mesofauna, macrofauna, and soil microbiota). In this context, pieces of evidence on the adverse effects of engineered nanoparticles (ENP) on the physicochemical and biological properties of soils are discussed in this paper. We have found a diversity of contradictory results. The summaries, findings, and conclusions of most of the investigations support the need to understand the biological or physicochemical transformation and transport of ENP in soil, and in the plant-organism relationship. Better understanding regarding the soil biota coupled with the ecological ENP behavior could ensure the safe use of ENP. Nanomaterials can change the physicochemical and biological properties of the soils; consequently, long-term in situ field trials are required, and meanwhile, land-application of nanomaterials should be limited to scientific experiments to fill knowledge gaps to not jeopardize the global food production or the environment and worldwide human health.
