“…The helical structures can be either double-or single-stranded and the uniform sugar-phosphate backbone can be as long as from several to million base-pairs, which help to produce different morphologies of electrode materials under adsorption-reduction, deposition, calcination, or hydrothermal processes. [42,43] The as-formed metal nanowires, carbon nanofibers (CNFs), oxide nanoclusters, sulfide nanosheets, etc. [44][45][46][47] exhibit excellent electrochemical performances in different applications.…”

Bio‐organisms with various architectures and versatile physiological functions provide a substantial bibliography for electrode design. To elucidate how bio‐organisms and bio‐schemes take effect in advanced electrode materials, this review sorts bio‐assisted construction into two categories, namely, biotemplating synthesis and biomimetic artificial fabrication. The former section summarizes unique characteristics of different biotemplates for electrode preparation, including “bottom‐up” structural designability of biomolecules, metabolism involving, and genetic alterable properties of biological cells, as well as, the structural regularity and integrity of bio‐tissues, with the aim to provide guidelines for manipulating bioarchitectures and endow biotemplating synthesis of electrodes with more designability. The later describes recent efforts in using bio‐prototypes to enhance the essential properties associated with advanced electrodes, including mechanical properties, wettability, mass transport, electron/charge transfer, and catalytic activity, with intensive concerns on the function principles of biomimetic designs in electrochemical systems. Then, advances in applications of bioderived and biomimetic electrode materials are summarized emphasizing how bio‐structures/components and bionic designs help to enhance the charging/discharging and electrocatalytic performance in specific electrochemical energy storage and conversion systems. Finally, future trends with prospects and challenges for developing new bioderived/biomimetic electrode materials, as well as, related conceptual innovation on bionics, are discussed in the last section.

“…These properties, such as tailored electron oscillation, [19] chirality, [20][21][22][23] surface-enhanced Raman scattering (SERS) and photoluminescence (PL) [24] find widespread utility in metal ion detection, [25] bioimaging, biosensing, [26,27] biomedicine [28,29] and bioanalysis. [30] As dynamic DNA nanostructures hold immense promise for medical, scientific, and technological exploration, [31][32][33][34] the reconfiguration of dynamic gold nanostructures formed molecular devices [35] driven by various physical or chemical stimuli [20] have drawn increasing attention for future application. By presenting various colors or circular dichroism (CD) signals that can be easily observed, dynamic gold nanostructures offer numerous opportunities for designing biochemical sensors at the singlemolecule level without any amplification processes and exhibit single-base mismatch DNA detection capability.…”

The combination of DNA nanotechnology and Nano Gold (NG) plasmon has opened exciting possibilities for a new generation of functional plasmonic systems that exhibit tailored optical properties and find utility in various applications. In this review, the booming development of dynamic gold nanostructures are summarized, which are formed by DNA self‐assembly using DNA‐modified NG, DNA frameworks, and various driving forces. The utilization of bottom‐up strategies enables precise control over the assembly of reversible and dynamic aggregations, nano‐switcher structures, and robotic nanomachines capable of undergoing on‐demand, reversible structural changes that profoundly impact their properties. Benefiting from the vast design possibilities, complete addressability, and sub‐10 nm resolution, DNA duplexes, tiles, single‐stranded tiles and origami structures serve as excellent platforms for constructing diverse 3D reconfigurable plasmonic nanostructures with tailored optical properties. Leveraging the responsive nature of DNA interactions, the fabrication of dynamic assemblies of NG becomes readily achievable, and environmental stimulation can be harnessed as a driving force for the nanomotors. It is envisioned that intelligent DNA‐assembled NG nanodevices will assume increasingly important roles in the realms of biological, biomedical, and nanomechanical studies, opening a new avenue toward exploration and innovation.

However, due to the absence of long-range ordered structures in biological templates, the mechanical performance of synthetic HAP is markedly lower than that of natural bone or dentin. For example, the Young's modulus of HAP mineralized using bacterial cellulose is ≈10.9 GPa, which is significantly lower than that of human dentin (≈22.5 GPa). [11] The low mechanical stiffness and toughness of artificial HAP biomaterials limit their biomedical applications. Hence, it is important to develop novel biological templates with long-range ordering to induce high-density stacking of HAP minerals at the macroscale.DNA is an attractive template for bottom-up nanofabrication because it can be artificially synthesized and its base pair sequence can be programmed. [15][16][17][18] The multiple supramolecular interactions and molecular recognition of DNA further broaden its biomedical applications. [19][20][21][22][23][24] In particular, DNA nanotechnology is increasingly being utilized for the mineralization of inorganic materials at the nanoscale. [15,[25][26][27] Recently, Liu et al. achieved the mineralization of mechanically strong calcium phosphate (CaP) nanoparticles ranging from 10 to 100 nm using self-assembled DNA frameworks. [28] However, Programmable base pair interactions at the nanoscale make DNA an attractive scaffold for forming hydroxyapatite (HAP) nanostructures. However, engineering macroscale HAP mineralization guided by DNA molecules remains challenging. To overcome this issue, a facile strategy is developed for the fabrication of ultrastiff DNA-HAP bulk composites. The electrostatic complexation of DNA and a surfactant with a quaternary ammonium salt group enables the formation of long-range ordered scaffolds using electrospinning. The growth of 1D and 2D HAP minerals is thus realized by this DNA template at a macroscale. Remarkably, the as-prepared DNA-HAP composites exhibit an ultrahigh Young's modulus of ≈25 GPa, which is comparable to natural HAP and superior to most artificial mineralized composites. Furthermore, a new type of dental inlay with outstanding antibacterial properties is developed using the stiff DNA-HAP. The encapsulated quaternary ammonium group within the dense HAP endows the composite with long-lasting and local antibacterial activity. Therefore, this new type of super-stiff biomaterial holds great potential for oral prosthetic applications.The ORCID identification number(s) for the author(s) of this article can be found under https://doi.org/10.1002/adma.202202180.
