“…The structural features of these replicas had dimensions of approximately 100 nm, but they also exhibited cathodoluminescence properties different from those of nanocasts. 114 From the air stable supersaturated europium-doped yttrium nitrate solution previously developed for 3D PBG crystal template infilling, 115 further wing scale casts were fabricated from Sericinus montelus specimens and where FESEM studies confirmed the nano-replication down to 20 nm. 116 Because of the super-hydrophobic surfaces of most butterfly wings, 117 precursors with strong impregnation that could homogeneously soak into wing templates are not easy to produce.…”

Through millions of years of evolutionary selection, nature has created biological materials with various functional properties for survival. Many complex natural architectures, such as shells, bones, and honeycombs, have been studied and imitated in the design and fabrication of materials with enhanced hardness and stiffness. Recently, more and more researchers have started to research the wings of butterflies, mostly because of their dazzling colors. It was found that most of these iridescent colors are caused by periodic photonic structures on the scales that make up the surfaces of these wings. These materials have recently become a focus of multidiscipline research because of their promising applications in the display of structural colors, and in advanced sensors, photonic crystals, and solar cells. This paper review aims to provide a perspective overview of the research inspired by these wing structures in recent years.

“…The captivating brilliance of natural opal gemstones arises from their internal ordered periodic structure, allowing them to exhibit a full spectrum of visual colors when viewed from different angles, a phenomenon distinct from coloration through pigments. − Photonic crystals , exemplified by artificial opals in structures are crafted through the periodic arrangement of materials with distinct refractive indices. The Bragg diffraction stemming from this orderly periodic structure acts as a barrier, preventing the transmission of specific wavelength bandsa phenomenon known as the photonic band gap (PBG). , The light waves in the PBG are forbidden to propagate in the photonic crystals, while other light waves can propagate without loss. , The PBG center wavelength (λ max ) of the opal structured photonic crystals follows Bragg’s diffraction law: λ max = 2 d n eff 2 − sin 2 θ d 111 = a 1 2 + 1 2 + 1 2 = 2 3 D n eff 2 = n sphere 2 f sphere + n air 2 false( 1 − f sphere false) …”

Photonic crystals (PCs) exhibit the ability to adjust their microstructure and structural color in response to environmental stimuli and have been applied in optical manipulation and visual sensing, which showcase dynamic adaptability to changing conditions. In this study, a bioderived composite hydrogel sensor was prepared utilizing fish collagen, acrylamide, N-isopropylacrylamide, and PCs for the dual visualization of strain and temperature. Fish collagen derived from tilapia skin enhanced its mechanical properties with a 1846.29% tensile strain. Glycerol contributed to both moisturization and temperature stability, preserving the material's mechanical integrity even under extreme conditions of 60 and −53 °C. The reflection peak of the sensor exhibited blue shifts of 146 nm with 10% compression and 120 nm with 12% tensile strain. Additionally, the reflection peak experienced a blue shift of 45 nm as the temperature rose from 25 to 37 °C, and this shift remained stable even after 10 cycles. Moreover, the sensor's ability to visualize strain and temperature remained consistent even after a period of 30 days. Given its mechanical robustness, moisture resistance, temperature resilience, and durability, the bioderived composite hydrogel sensor stands as a viable choice for ongoing, prolonged monitoring of strain and temperature in wearable research studies.

The structural characteristics of natural species have been optimized by natural selection for millions of years. They offer specific functions much more effectively than artificial approaches. Morphology genetic materials utilize morphologies gleaned from natural selection into their hierarchical structures. The combination of natural morphologies and manually selected functional materials makes these novel materials suitable for many applications. This review focuses on the strategies by which the structures and functions of natural species can be utilized. Specific functions inherited from both the natural microstructures and coupled functional materials are highlighted with regard to various applications, including photonics, light-harvesting, surface-enhanced Raman scattering (SERS), and electrodes for supercapacitors and batteries, as well as environmentally friendly materials.
