“…From the mechanical point of view, instead, the measured properties can be of interest for the design and optimization of new bio-inspired composite materials (Libonati et al, 2016;Gu et al, 2017;Pugno and Valentini, 2019), e.g. multilayer composites for shell structures.…”

In this work we evaluate the mechanical properties of Chamelea gallina shells, collected at various locations in the Adriatic Sea, through compression tests. We present an analytical model for the extraction of the material Young's modulus and ultimate strength, based on the approximation of the valves with a simpler geometry. The effect of porosity and the computation of the energy dissipated at fracture are also discussed. Results show a dependence of the mechanical performance on the location at which the samples were collected, i.e. latitude, and thus the environmental factors can affect the rigidity and strength of the shells. These findings confirm and integrate preliminary results published in a previous work. Graphical Abstract: KeywordsClam shells, abiotic factors, aragonite, analytical modelling, fracture.

“…Regarding the type of biological activity required to produce these changes, fermentation is one example and has emerged as a means of potentially introducing novel composite properties over time. [194] Utilizing cellular fermentation processes, Zhang et al created a living system in which bulk material porosity could be altered according to cellular activity. In the presence of nutrients, yeast embedded within acrylamide hydrogels generated carbon dioxide, leading to the formation of a highly porous hydrogel.…”

The emergence of novel techniques in biology and material science, coupled with greater understandings of cell-material interactions, have given rise to the creation of living materials and bioarchitectures imbued with engineered living behaviors. These multidimensional materials and constructs capable of performing programmable and time-or stimuli-dependent activities, namely 4D behaviors, may do so as a result of material features alone, or as a product of incorporated biological or cellular agents. This review discusses fabrication strategies employed in the development of 4D living materials and examples of their 4D activities driven by cellular events or processes. The fabrication strategies investigated throughout are focused on those that facilitate the responsive, functional transformation of the 3D structure with the time that extends beyond changes driven solely by material features, and enable an increase in the cell-dependent functional capacity of the construct. Living materials comprised of cells and their own products, as well as both cells and added non-living materials are investigated. Further, the authors analyze how material complexities and biological complexities have thus far been interfaced to allow for intricate living behaviors, and discuss the design considerations and challenges encountered in developing living materials. Finally, the future directions of living materials are outlined.

“…[147] While a surprising and niche approach, this could be applied to the production of multiple biomaterials. [148] On a larger scale, it is generally more challenging to make non-oxide graphene composites with silk fibroin because conventional extraction of the protein from spider dragline or silkworm cocoons is performed in aqueous solution, incompatible with the highly hydrophobic graphene. Instead, unconventional solvents such as hexafluoroisopropanol (HFIP) [149] and CaCl 2 / formic acid (FA) [150] may be used to produce composites with high graphene content.…”

It can be difficult to know where to begin when considering the research opportunities of a material with such outstanding potential as graphene. When searching for a “killer application,” the researcher often neglects to query the world around them, forgetting that nature has been evolving for billions of years to elegantly solve every day problems. Bioinspiration is an intelligent strategy to nucleate new ideas and speed up the innovation process by providing ready‐made prototypes. Graphene is uniquely placed to take advantage of this approach thanks to its superlative properties and versatile nature. In this review, the state‐of‐the‐art in the bioinspired design of graphene‐based materials has been analyzed, and three distinct sources of inspiration have been identified: natural functions, such as adhesion and actuation; natural structures, such as layers and pores; and natural processes, such as surface functionalization and biomineralization. Implementing this philosophy into further graphene research will provide new ways to solve problems and suggest novel applications that may not otherwise be considered.
