“…The several beneficial properties already stated as well as its potential as supporting material are expected to make CNF the platform of choice in the development of bioactive interfaces. Bacterial cellulose, with its a high crystallinity and purity (Castro et al, 2011) has attracted interest especially in applications requiring contact with tissue or otherwise demanding nontoxicity (Zang et al, 2014). BC has been suggested for skin care applications such as for wound dressing (Fu, Zhou et al 2013) and their pellicles are known to be able to bind a vast amount of water, which is beneficial in skin burns and can potentially absorb exudates.…”

“…Reproduced with permission from ref. [123,127,128,[133][134][135] Sano et al [124] used electric fields to produce oxygen in culture medium. Since G. xylinus is an aerobic bacterium, oxygen induced their ordered motions, which made them biosynthesize ordered cellulose fibers.…”

“…The movement of G. xylinus on template was restricted by oxygen availability and by the groove pattern. BC films with grid and strip structures were also obtained through precise control of culture conditions [128,129]. In addition, genetic manipulation is a promising technique to achieve this goal.…”

Microbes are important part of life that vary in sizes and shapes, diverse surface chemistry and biology, and porous nature of their cell walls. Besides their importance in industrial processes such as fermentation, these serve as biotemplates and provide a biomimetic approach for fabrication of multifarious complex constructs with predefined features, ordered composites and hybrid nanomaterials, microdevices, and micro/nanorobots through various strategies. The template or building blocks for such approaches can be bacterial, algal, and fungal cells or virus particles. Here, we have summarized recent advancements in biofabrication based on live microbes. Using engineering approaches and suitable methods, live microbes can be manipulated as functional Bmicro/nanodevices and -robots^to further perform biological functions such as replication, distribution, motility, formation of colonies, and secretion of metabolites at will. Biofabrication based on microbes provides effective methods to control and manipulate microbes as functional live building blocks to create micro/nanodevices and -robots for biomedical and energy applications.

“…[1][2][3] Numerous different natural polymer-based porous scaffolds have attracted considerable attention due to their significant potentials of fulfilling these features simultaneously. [4][5][6] Alginate (Alg), an anionic linear polysaccharide consisting of 1,4-linked β-D-mannuronic acid (M) and α-Lguluronic acid (G) residues, [7][8][9] has been considered as a promising porous scaffold material because of its good biocompatibility, biodegradability, nontoxicity, and nonimmunogenicity. [10][11][12][13] Alg is easy to form stable 3D gel networks with the so-called "eggbox" structure through ionotropic crosslinking.…”

Three‐dimensional (3D) homogenous scaffolds composed of natural biopolymers have been reported as superior candidates for bone tissue engineering. There are still remaining challenges in fabricating the functional scaffolds with gradient structures to similar with natural bone tissues, as well as high mechanical properties and excellent affinity to surround tissues. Herein, inspired by the natural bone structure, a gradient‐structural scaffold composed of functional biopolymers was designed to provide an optimized 3D environment for promoting cell growth. To increase the interactions among the scaffolds, dopamine (DA) was employed to modify alginate (Alg) and needle‐like nano‐hydroxyapatite (HA) was prepared with quaternized chitosan as template. The obtained dopamine‐modified alginate (Alg‐DA) and quaternized chitosan‐templated hydroxyapatite (QCHA) were then used to fabricate the porous gradient scaffold by “iterative layering” freeze‐drying technique with further crosslinking by calcium ions (Ca2+). The as‐prepared Alg‐DA/QCHA gradient scaffolds were possessed seamlessly integrated layer structures and high levels of porosity at around 77.5%. Moreover, the scaffolds showed higher compression modules (1.7 MPa) than many other biopolyermic scaffolds. The gradient scaffolds showed appropriate degradation rate to satisfy with the time of the bone regeneration. Both human chondrocytes and fibroblasts could adhesive and growth well on the scaffolds in vitro. Furthermore, an excellent osteogenetic activity of the gradient scaffold can effectively promote the regeneration of the bone tissue and accelerate the repair of the bone defects in vivo, compared with that of the scaffold with the homogenous structure. The novel multilayered scaffold with gradient structure provided an interesting option for bone tissue engineering. © 2019 Wiley Periodicals, Inc. J Biomed Mater Res Part A: 107A: 1615–1627, 2019.
