“…The “protein corona” was observed to be denser in B. subtilis AgS nanoparticles most probably due to their higher Zeta potential (−37.82 mV) which was 20 times greater than E. coli and 10 times than S. oneidensis . [ 84 ] This work paves the way for further studies aiming to understand the origin of interaction between the protein and the nanoparticle surface. As seen in this section, microbial biosynthesis of nanoenzymes, their conjugation with cells that can function as sources or sinks of electrons and their coupling with natural or biomimetic envelopes provide a plethora of options for manipulating their physicochemical and catalytic properties that have been explored in numerous applications and that have been investigated to explore their molecular mechanisms of action as detailed in the next section.…”

“…[ 83 ] As seen above, the properties of biosynthesized nanoparticles are determined by their interaction with the macromolecules present in both intra and extracellular biogenic pathways. [ 84 ] Thus, understanding the mechanisms underlying this process will lead to tailored nanoenzymes with improved catalytic performance.…”

As a powerful tool, nanoenzyme electrocatalyst broadens the ways to explore bioinspired solutions to the world's energy and environmental concerns. Efforts of fashioning novel nanoenzymes for effective electrode functionalization is generating innovative viable catalysts with high catalytic activity, low cost, high stability and versatility, and ease of production. High chemo‐selectivity and broad functional group tolerance of nanoenzyme with an intrinsic enzyme like activity make them an excellent environmental tool. The catalytic activities and kinetics of nanoenzymes that benefit the development of nanoenzyme‐based energy and environmental technologies by effectual electrode functionalization are discussed in this article. Further, a deep‐insight on recent developments in the state‐of‐art of nanoenzymes either in terms of electrocatalytic redox reactions (viz. oxygen evolution reaction, oxygen reduction reaction, nitrogen reduction reaction and hydrogen evolution reaction) or environmental remediation /treatment of wastewater/or monitoring of a variety of pollutants. The complex interdependence of the physicochemical properties and catalytic characteristics of nanoenzymes are discussed along with the exciting opportunities presented by nanomaterial‐based core structures adorned with nanoparticle active‐sites shell for enhanced catalytic processes. Thus, such modular architecture with multi‐enzymatic potential introduces an immense scope of making its economical scale‐up for multielectron‐fuel or product recovery and multi‐pollutant or pesticide remediation as reality.

“…A recent example has come from the study of Zhang et al (2017), which showed how CdSe quantum dots biosynthesis can be improved through genetic modification of the ATP metabolism pathway in yeast S. cerevisiae [107]. Biotechnological approaches based on genetic engineering and recombinant technologies could allow the identification of sequences of gene involved in nanoparticle synthesis and a possible heterologous expression (i.e., controlled expression of one or more gene sequences in a host organism) to enhance nanomaterial production efficiency [91]. The bacterium E. coli is a highly efficient model host microorganism that has been exploited as heterologous expression system for phytochelatin synthase and/or metallothionein for the in vivo synthesis of various metal nanoparticles (e.g., CdSeZn, PrGd, CdCs, and FeCo) never synthesized before by chemical methods [108,109] or cadmium selenide quantum dots [110].…”

Microbial Nanotechnology: Challenges and Prospects for Green Biocatalytic Synthesis of Nanoscale Materials for Sensoristic and Biomedical Applications

Nanomaterials are increasingly being used in new products and devices with a great impact on different fields from sensoristics to biomedicine. Biosynthesis of nanomaterials by microorganisms is recently attracting interest as a new, exciting approach towards the development of ‘greener’ nanomanufacturing compared to traditional chemical and physical approaches. This review provides an insight about microbial biosynthesis of nanomaterials by bacteria, yeast, molds, and microalgae for the manufacturing of sensoristic devices and therapeutic/diagnostic applications. The last ten-year literature was selected, focusing on scientific works where aspects like biosynthesis features, characterization, and applications have been described. The knowledge, challenges, and potentiality of microbial-mediated biosynthesis was also described. Bacteria and microalgae are the main microorganism used for nanobiosynthesis, principally for biomedical applications. Some bacteria and microalgae have showed the ability to synthetize unique nanostructures: bacterial nanocellulose, exopolysaccharides, bacterial nanowires, and biomineralized nanoscale materials (magnetosomes, frustules, and coccoliths). Yeasts and molds are characterized by extracellular synthesis, advantageous for possible reuse of cell cultures and reduced purification processes of nanomaterials. The intrinsic variability of the microbiological systems requires a greater protocols standardization to obtain nanomaterials with increasingly uniform and reproducible chemical-physical characteristics. A deeper knowledge about biosynthetic pathways and the opportunities from genetic engineering are stimulating the research towards a breakthrough development of microbial-based nanosynthesis for the future scaling-up and possible industrial exploitation of these promising ‘nanofactories’.
