“…Dragline spider silks have been extensively studied with the long-term goal often being biomimicry [1,2,3]. Dragline spider silks are protein-based biopolymers and understanding the proteins’ primary and secondary structures are critical steps in the goal of reproducing synthetic versions of this extraordinary fiber [4].…”

Solid-state NMR and molecular dynamics (MD) simulations are presented to help elucidate the molecular secondary structure of poly(Gly-Gly-X), which is one of the most common structural repetitive motifs found in orb-weaving dragline spider silk proteins. The combination of NMR and computational experiments provides insight into the molecular secondary structure of poly(Gly-Gly-X) segments and provides further support that these regions are disordered and primarily non-β-sheet. Furthermore, the combination of NMR and MD simulations illustrate the possibility for several secondary structural elements in the poly(Gly-Gly-X) regions of dragline silks, including β-turns, 310-helicies, and coil structures with a negligible population of α-helix observed.

“…Researchers have used the synthesis of structural proteins to produce polymers for fibres that may become commercially useful in the future (Gosline et al 1995;Reed et al 2009). Dzenis (2004) suggested an electrospinning technique to produce 2 mm diameter continuous fibres from polymer solutions that are somewhat similar to the spider silk fibres.…”

Nature has developed materials, objects and processes that function from the macroscale to the nanoscale. These have gone through evolution over 3.8 Gyr. The emerging field of biomimetics allows one to mimic biology or nature to develop nanomaterials, nanodevices and processes. Properties of biological materials and surfaces result from a complex interplay between surface morphology and physical and chemical properties. Hierarchical structures with dimensions of features ranging from the macroscale to the nanoscale are extremely common in nature to provide properties of interest. Molecularscale devices, superhydrophobicity, self-cleaning, drag reduction in fluid flow, energy conversion and conservation, high adhesion, reversible adhesion, aerodynamic lift, materials and fibres with high mechanical strength, biological self-assembly, antireflection, structural coloration, thermal insulation, self-healing and sensory-aid mechanisms are some of the examples found in nature that are of commercial interest. This paper provides a broad overview of the various objects and processes of interest found in nature and applications under development or available in the marketplace.

“…Biological engineering has helped to enhance the effi cacy of many fi elds. Many technological problems are solved by biological engineering for example it helped in nanotechnology, cell culture methods [10] and research materials [11]. 3D bioprinting application to biomimicry involves the formation of identical, cellular and extracellular components of tissues [12].…”

3D bioprinting is computer-aided technology used to generate 3D models of organs. Employing this technique, organ and tissues are generated according to the patient body. 3D structures are formed by the deposition of bioink. This bioink can be natural or synthetic bionink. For in vitro implantation, the tissue is fi rst incubated in a bioreactor, however, in in vivo there is no prerequisite incubation required, rather cells are directly implanted. Bioprinting consists of various steps involving imaging, design approach, choice of material, cell selection and printing of tissue construct.3D bioprinting has two main approaches, i.e. cellular and a-cellular. Cellular bioprinting can be inkjet based, stereolithography based, laser induced forward transfer (LIFT) and extrusion based. Acellular bioprinting is extrusion based and laser based. Tissues of various organs are formed using 3D bioprinting involving blood vessels, bone, cartilage, heart, kidneys, and that of the skin and neurons. However, bioprinting of micro organs and the selection of suitable bioink is a diffi cult task. Bioprinting has various limitations that lead to the development of 4D bioprinting. This review paper will help you to understand the basic technique of 3D bioprinting, its application, limitations and new advancements that help to enhance the effi cacy of this technique.
