“…It was observed that such structures had the property to catalyse redox reactions and possessed optical properties similar to that of nanoparticles. Similar to Sugunan et al, 49 Rehman et al 51 prepared a wire like structure by coating gold nanoparticles onto Aspergillus niger hypae. The growth of gold nanoparticle coated hyphal wire was achieved by growing the fungus in a nutrient medium.…”

“…These gold-microwires can be further converted into microtubules through super critical CO 2 extraction . In contrast to CO 2 extraction, the extraction of fungal organic template to produce porous microwires can also be synthesized by using heat treatment . In another study, gold-nanowires were prepared through self-organization of colloidal nanoparticles onto A.…”

Biofabrication, referring to engineering of complex constructs with desired features using living biotemplates, is a new fascinating technology. Microbes as exceptional templates provide a biomimetic approach to obtain amazingly ordered nano-, micro-, and meso-structured materials owing to diversity in their sizes and shapes, presence of a variety of chemical functional groups on their surfaces, and intrinsically porous structure of their cell walls. As biotemplates, microbes can be utilized for synthesis of novel bionanomaterials, microdevices, and micro/nanorobots, etc. by using various bottom-up approaches. Here, we summarized the recent advancements in biofabrication based on microbes, from nano to mesoscopic size, from viruses to true-living microbes, from prokaryotes to eukaryotes, and from unicellular to multicellular microbes. It reviews the role of viruses, bacteria, fungi, and algae as structural templates in biofabrication of various bionanomaterials for diverse applications and provides new insights for future development of fabrication technology by using these microbes.

“…Given the rapid growth of mycelia in comparison to other multicellular tissues, the ease of controlling the final form through the use of molds, and the potential of altering the physicochemical properties of the hyphae, this technology has great promise for the wide-scale implementation for engineered living materials. Hyphae biotemplating would greatly expand the spectrum of uses for mycelial materials by combining the rapid growth potential of fungi with the desirable material properties of inorganics, as demonstrated in several studies [116, 117] . A recent publication has also characterized the physical properties of the mycelial materials and potential routes of altering these properties by simply adjusting the feedstock [118] .…”

Engineered Living Materials: Prospects and Challenges for Using Biological Systems to Direct the Assembly of Smart Materials

Vast potential exists for the development of novel, engineered platforms that manipulate biology for the production of programmed advanced materials. Such systems would possess the autonomous, adaptive, and self-healing characteristics of living organisms, but would be engineered with the goal of assembling bulk materials with designer physicochemical or mechanical properties, across multiple length scales. Early efforts toward such engineered living materials (ELMs) are reviewed here, with an emphasis on engineered bacterial systems, living composite materials which integrate inorganic components, successful examples of large-scale implementation, and production methods. In addition, a conceptual exploration of the fundamental criteria of ELM technology and its future challenges is presented. Cradled within the rich intersection of synthetic biology and self-assembling materials, the development of ELM technologies allows the power of biology to be leveraged to grow complex structures and objects using a palette of bio-nanomaterials.
