Confined-space synthesis of nanostructured anatase, directed by genetically engineered living organisms for lithium-ion batteries

Bacteria play an important role in the calcification process of natural minerals and within organisms ( Table 1). It is Microbe-mediated mineralization is ubiquitous in nature, involving bacteria, fungi, viruses, and algae. These mineralization processes comprise calcification, silicification, and iron mineralization. The mechanisms for mineral formation include extracellular and intracellular biomineralization. The mineral precipitating capability of microbes is often harnessed for green synthesis of metal nanoparticles, which are relatively less toxic compared with those synthesized through physical or chemical methods. Microbe-mediated mineralization has important applications ranging from pollutant removal and nonreactive carriers, to other industrial and biomedical applications. Herein, the different types of microbe-mediated biomineralization that occur in nature, their mechanisms, as well as their applications are elucidated to create a backdrop for future research.

“…Using cell surface display technique, Escherichia coli can be genetically engineered to display repeat titanium‐binding peptides (R5) on the cell surface ( Figure a). The engineered cells serve as a framework to direct the confined growth of TiO 2 onto cell surface, which leads to the formation of a rod‐shaped architecture composed of cells and assembled TiO 2 nanoparticles (Figure b–d) .

In nature, the biomineralization processes of living organisms produce a wide range of organic-inorganic hybrid materials to achieve various functions. In particular, egg shells can provide extra protection for embryos and maintain air exchange. Inspired by such phenomena, it is assumed that the engineering of organisms with biomimetic materials can lead to significant improvement in organism function. This review summarizes recent progress in biomineralization-based techniques for organism engineering, and demonstrates the therapeutic potential enabled by these techniques. The design and synthesis approaches of biomineralization-based engineering are systemically introduced to guide the controlled modification of different organisms including viruses, bacteria, cells, and proteins using in situ biomineralization, bottom-up self-assembly, chemical and genetic engineering. Tailored organisms promise delivery, protection, cell therapy, vaccine improvement as well as therapeutic detection and imaging. The present review aims to propose a biomineralization-based strategy to promote functional evolution of these organisms, which promises to meet the increasing demand for new therapeutic purpose.

Natural structure‐forming processes found in biological systems are fantastic and perform at ambient temperatures, in contrast with anthropogenic technologies that commonly require harsh conditions. A new research direction “bioprocess‐inspired fabrication” is proposed to develop novel fabrication techniques for advanced materials. Enamel, an organic–inorganic composite biomaterial with outstanding mechanical performance and durability, is formed by repeating the basic blocks consisting of columnar hydroxyapatite or fluorapatite and an organic matrix. Inspired by the enamel formation process, a microscale additive manufacturing method is proposed for achieving a multilayered organic–inorganic columnar structure. In this approach, rutile titanium dioxide (TiO2) nanorods, polymers, and graphene oxide (GO) are sequentially assembled in a layer‐by‐layer fashion to form an organic–inorganic structure. In particular, GO serves as a substrate for TiO2 nanorods and interacts with polymers, jointly leading to the strength of the composites. Impressively, this enamel‐like structure material has hardness (1.56 ± 0.05 GPa) and ultrahigh Young's modulus (81.0 ± 2.7 GPa) comparable to natural enamel, and viscoelastic property (0.76 ± 0.12 GPa) superior to most solid materials. Consequently, this biomimetic synthetic approach provides an in‐depth understanding for the formation process of biomaterials and also enables the exploration of a new avenue for the preparation of organic–inorganic composite materials.
