“…[47][48][49] One typical example is magnetotactic bacteria, a unique species of microorganism capable of biomineralizing endogenous magnetite NPs (known as the magnetosomes, which consist of membrane bounds and nanosized crystals) (Figure 2a). [50][51][52] The biologically synthesized magnetosomes can be organized in one or multiple magnetic chains, to endow the magnetotactic bacteria with unique capability to orient and even migrate along geomagnetic field lines. These biosynthesized magnetic MNPs exhibit fascinating advantages in terms of controlling crystal growth and structural properties.…”

Microorganisms become new sources for fabricating intricate micro/nano structures via bottom‐up approaches. Produced from nature, microorganism biotemplates exhibit unique structural and material features over thousands of years of revolution. They are considerably superior and cost‐effective for fabricating complex and heterogeneous structures when compared to other micro/nanofabrication techniques. Herein, the recent advances in biologically driven micro/nanofabrication, assembly, and actuation based on microorganisms are consolidated. Detailed development and recent advances of micro/nanoparticle fabrication, their ordered assembly, and controlled actuation properties, as well as certain typical engineering application examples, are mainly involved. The developing perspectives and challenges of microorganism‐based micro/nanofabrication are also discussed, aiming to inspire the relevant researches and promote the development in this field.

“…Magnetic resonance imaging uses different attenuation in different structural environments; the electromagnetic wave is emitted after the applied magnetic field, and the image is formed through the position and type of a certain atomic nucleus. ,− It is the physical process that the spin energy level of an atomic nucleus with a nonzero magnetic moment undergoes Zeeman splitting under the action of an external magnetic field, and resonantly absorbs a certain frequency of RF radiation. ,, Relaxation is divided into transverse relaxation ( T 2 ) and longitudinal relaxation ( T 1 ). Transverse relaxation is the process of gradual decrease of transverse magnetization, and longitudinal relaxation is the process of gradual recovery of longitudinal magnetization.…”

Intracellular biosynthetic nanomaterials offer tremendous opportunities for chemical biomedical imaging. A wide range of biologically active tissues are available for biosynthesis, including cells, bacteria, plants, and viruses. Nanomaterials synthesized by intracellular biomineralization with outstanding biosafety and optical properties attract unique attention. Herein, an overview of biosynthetic tunable nanomaterials within active biological tissues for chemical biomedical imaging is presented. The synthetic mechanisms and nanostructures of biosynthetic nanomaterials are summarized from the perspective of different active organisms. The ability of biosynthesis is commonly used for green synthesis of metal nanoparticles compared to those synthesized by physical or chemical methods. The tunable characteristics of these nanoparticles make it possible to utilize them as fluorescence imaging, surface-enhanced Raman spectral mapping, nuclear magnetic resonance imaging, and other biomedical photonics tools. Importantly, current issues, insights, and future tendencies of development are presented based on current biosynthetic optical nanomaterials for chemical biomedical imaging. This paper provides the summary of biosynthetic optical nanomaterials and a critical assessment of potential biomedical imaging applications in this emerging field, laying the foundation for future studies.

“…A common approach to improving tanshinone production using S. miliorrhiza hairy roots is to overexpress transcription factors involved in the tanshinone biosynthetic pathway. Examples of this approach include overexpression of SmMYB9b (Zhang et al, 2017), SmMYB98 (Hao et al, 2020), SmbHLH10 (Xing et al, 2018b) and SmbHLH148 (Xing et al, 2018a).…”

While plants are an abundant source of valuable natural products, it is often challenging to produce those products for commercial application. Often organic synthesis is too expensive for a viable commercial product and the biosynthetic pathways are often so complex that transferring them to a microorganism is not trivial or feasible. For plants not suited to agricultural production of natural products, hairy root cultures offer an attractive option for a production platform which offers genetic and biochemical stability, fast growth, and a hormone free culture media. Advances in metabolic engineering and synthetic biology tools to engineer hairy roots along with bioreactor technology is to a point where commercial application of the technology will soon be realized. We discuss different applications of hairy roots. We also use a case study of the advancements in understanding of the terpenoid indole alkaloid pathway in Catharanthus roseus hairy roots to illustrate the advancements and challenges in pathway discovery and in pathway engineering.
