“…Concerning the self-consistency of the experimental results, the preparation and multiplication of monoclonal bacteria are critical. This experiment, different from the template synthesis experiments 15 16 , employed bioactive gram-negative bacteria. To get a single wall, we chose prokaryotic bacteria instead of eukaryotic bacteria like yeast 15 .…”

“…This experiment, different from the template synthesis experiments 15 16 , employed bioactive gram-negative bacteria. To get a single wall, we chose prokaryotic bacteria instead of eukaryotic bacteria like yeast 15 . To achieve a spherical shape with a length-to-diameter ratio of 1:1, instead of a larger length-to-diameter ratio 16 , we fed bacteria with a much higher concentration of oxyanions to manipulate them to shrink into a spherical shape, making microcapsules with a single, round, and thin wall (<30 nm).…”

“…Some of the alternative methods require templates 12 , some a temperature as high as 500 °C 13 , and some a high pressure 14 . As for the resulting structure, the template synthesis method utilizing the yeast template brings about a core-shell structure 15 , instead of one with a single wall, and the one utilizing the E. coli template produces a structure with length-to-diameter ratio of 1.7:0.8, and is not spherical. 16 .…”

We present a method, the bacterial mineral excretion (BME), for synthesizing two kinds of microcapsules, sodium tungstate and sodium molybdate, and the two metal oxides' corresponding nanoparticles—the former being as small as 22 nm and the latter 15 nm. We fed two strains of bacteria, Shewanella algae and Pandoraea sp., with various concentrations of tungstate or molybdate ions. The concentrations of tungstate and molybdate were adjusted to make microcapsules of different length-to-diameter ratios. We found that the higher the concentration the smaller the nanoparticles were. The nanoparticles came in with three length-to-diameter ratios: 10:1, 3:1 and 1:1, which were achieved by feeding the bacteria respectively with a low concentration, a medium concentration, and a high concentration. The images of the hollow microcapsules were taken via the scanning electron microsphere (SEM). Their crystal structures were verified by X-ray diffraction (XRD)—the crystal structure of molybdate microcapsules is Na2MoO4 and that of tungstate microcapsules is Na2WO4 with Na2W2O7. These syntheses all were accomplished under a near ambient condition.

This review covers recent progress and advancements in bio‐templating nanomaterials for use in energy applications. Viruses, bacteria, and fungus, as well as plant and animal biomasses such as woods, coffee grounds, and crab shells, can be used as the templates or carbon sources for metal‐ and carbon‐based nanomaterials. Here we provide an overview of each of these materials as a template, with emphasis on the synthesis methods and qualities of nanomaterials fabricated using these templates. Research in this field is understandably diverse, as such, we aim to further its development by providing a timely summary of current research. We anticipate that this field will continue to prove highly applicable to the salient and growing topics of renewable energy.
