The lamellar structure and biomimetic properties of a fish scale matrix

Abstract

A preparation technology for a fish scale matrix is shown, and its lamellar structure and biomimetic properties are studied.

A novel lamellar structural biomaterial and its effect on bone regeneration

“…22,25 According to our previous research, FS is composed of multilayered collagen bers. 17 The FTIR spectra recorded for FS showed typical bands for type I collagen: amide A, amide B, amide I, amide II, and amide III. We observed that the band amide A has been moved to lower frequencies due to the loss of binding water in collagen and the conformational changes of collagen molecules.…”

“…The preparation method was based on our previous research. 17 C. idella sh scales about 2.5 cm-diameter and 1000 g weight, were collected (Chengdu, Sichuan Province, China), and then washed at 15 C in turn with distilled water, mixed solvents, and buffers to remove mucopolysaccharides, proteins, and fats. The scales were then immersed in 10% EDTA solution at 4 C for decalcication for about 4 h, then cleaned with water and incubated in acetic acid solution at 4 C for 1 h to obtain the basal plates from the scales.…”

“…In our previous work, it was shown that a sh scale collagen matrix has a layered structure, special physical parameters, and biological characteristics, which can ensure sufficient time and space for bone regeneration. 17 In this study, based on the fact that Ctenopharyngodon idella is one of the largest freshwater shes in China and its scale utilisation rate is low, we described the preparation of a collagen membrane (FS) with high mechanical strength and antienzyme degradation ability by using the multi-level structure of sh scales. It is intended to be used as a guided tissue regeneration material, and its physical and chemical properties, in vitro degradation, biocompatibility, and in vivo osteogenic activity were preliminarily evaluated.…”

A Third Luminous Shark Family: Confirmation of Luminescence Ability for Zameus squamulosus (Squaliformes; Somniosidae)

“…In another tissue form a luminous shark, E. spinax, bioluminescence transmittance across the dorsal spine was evaluated to 10 % (5), while in a luminous Gasteropoda, Hinea brasiliana , through a specific shell architecture, the transmittance was measured to 63% (27). Comparatively in a nonluminous freshwater teleost, Ctenopharyngodon idella , a transmittance value of 20–30% was estimated for the dermal scale (28). Our value is in the high range of transmittance suggesting a significant role in light transmission.…”

Fish Scales and Their Biomimetic Applications

“…These fibers of collagen demonstrate a sliding behavior as the tooth penetrates, which also provides lamellar sliding resulting in tension of the soft fibers and compression of the hard-bony shells (limiting layer), resulting in tooth fracture of hampering (Yang et al, 2014). Similarly, the puncture resistant property in scales of carp and arapaima are found to be advantageous against physical threats, which can resist failure at even strain FIGURE 4 | Orientation of collagen fibers (in red) in eight-layered lamellae of grass carp under SEM (Feng et al, 2020).…”
