“…However, because of their long evolution process, beetle elytra possess a remarkable biological structure that exhibits several unique biological functions. For example, the structural color of the surfaces of beetle elytra is a typical instance of the combination of a subtle fine structure and camouflage [12–14]. Additionally, the inner three-dimensional structure of elytra and their corresponding biological functions, which not only facilitate flight but also protect the main body of the insect, are considered as an advanced evolutionary biological system that is both lightweight and high strength and exhibits excellent mechanical performance [15–17].…”

For developing lightweight and high-strength biomimetic sandwich structures, this study investigates the influence of honeycomb dimensions and forming methods on the mechanical properties of beetle elytron plates relative to honeycomb plates via compression experiments and the finite element method. The results indicate that the trabecular-honeycomb core structure in beetle elytron plates can increase the compressive strength by approximately 50% and double the energy absorption capacity of honeycomb plates with the same material costs. Furthermore, the influence of three types of forming methods on the compressive properties of beetle elytron plates is investigated by comparing the different deformation modes of these structures with those of honeycomb plates. Based on these findings, application recommendations regarding the forming methods of beetle elytron plates are presented to facilitate the structural design and preparation techniques according to the performance requirements of different fields, which will accelerate the industrial application of these biomimetic structures.

“…with brilliant colors. [1][2][3] In fact, the living organisms usually benefit from the optical signals hidden behind the colors, which originate from the nanosized photonic crystal structure inside the natural creatures. Since the concept of photonic crystals was put forward, [4,5] the use of photonic crystals to construct materials with structural colors has become a research hotspot for scientists.…”

As a nanoscale renewable resource derived from lignocellulosic materials, cellulose nanocrystals (CNCs) have the features of high purity, high crystallinity, high aspect ratio, high Young's modulus, and large specific surface area. The most interesting trait is that they can form the entire films with bright structural colors through the evaporation‐induced self‐assembly (EISA) process under certain conditions. Structural color originates from micro‐nano structure of CNCs matrixes via the interaction of nanoparticles with light, rather than the absorption and reflection of light from the pigment. CNCs are the new generation of photonic liquid crystal materials of choice due to their simple and convenient preparation processes, environmentally friendly fabrication approaches, and intrinsic chiral nematic structure. Therefore, understanding the forming mechanism of CNCs in nanoarchitectonics is crucial to multiple fields of physics, chemistry, materials science, and engineering application. Herein, a timely summary of the chiral photonic liquid crystal films derived from CNCs is systematically presented. The relationship of CNC, structural color, chiral nematic structure, film performance, and applications of chiral photonic liquid crystal films is discussed. The review article also summarizes the most recent achievements in the field of CNCs‐based photonic functional materials along with the faced challenges.

“…Atomic force microscopy (AFM) is capable of imaging, manipulating, and quantifying the mechanical properties at atomic length scale . Nanoindentation probes the properties at nanometer length scale, and is a versatile technique for mechanical testing of a diversity of specimens, from soft tissues to hard bones with impressive spatial resolution of the order of few tens to few hundreds of nanometer . Nanotribological investigations to probe wear properties of specimens has resulted in enhanced understanding of contact mechanics in biospecies, such as cell adhesion on scaffold surface, abrasion of implants due to body fluids and neighboring tissues, and friction between surgical instruments and organs/tissues they make contact with during surgery .…”

Nanomechanics has played a vital role in pushing our capability to detect, probe, and manipulate the biological species, such as proteins, cells, and tissues, paving way to a deeper knowledge and superior strategies for healthcare. Nanomechanical characterization techniques, such as atomic force microscopy, nanoindentation, nanotribology, optical tweezers, and other hybrid techniques have been utilized to understand the mechanics and kinetics of biospecies. Investigation of the mechanics of cells and tissues has provided critical information about mechanical characteristics of host body environments. This information has been utilized for developing biomimetic materials and structures for tissue engineering and artificial implants. This review summarizes nanomechanical characterization techniques and their potential applications in healthcare research. The principles and examples of label-free detection of cancers and myocardial infarction by nanomechanical cantilevers are discussed.
