TLDR
By close analysis of the force spectroscopy curves, additional information can be obtained about the molecules and their bonds to the native constructs and how they appear in single molecule forceSpectroscopy measurements are found.Citations

Nature’s hierarchical materials
Peter Fratzl,Richard Weinkamer +1 more
TL;DR: In this paper, the basic principles involved in designing hierarchical biological materials, such as cellular and composite architectures, adapative growth and as well as remodeling, are discussed, and examples that are found to utilize these strategies include wood, bone, tendon, and glass sponges.

Biomimetic Model Systems for Investigating the Amorphous Precursor Pathway and Its Role in Biomineralization
TL;DR: This review aims to provide a link between the prior literature and the new literature, which might be useful to newcomers in the field, and demonstrate that there may be certain unifying principles found in biomineral systems that seem widely diverse, such as from diatoms, to mollusk shells, to vertebrate bones and teeth.
Journal ArticleDOI
Merger of structure and material in nacre and bone - Perspectives on de novo biomimetic materials
TL;DR: In contrast to synthetic materials, evolutionary developments in biology have resulted in materials with remarkable structural properties, made out of relatively weak constituents, arranged in complex hierarchical patterns as discussed by the authors, which can exhibit superior levels of strength and toughness.

Tough and Self-Healing Hydrogels Formed via Hydrophobic Interactions
TL;DR: Results of dynamic light scattering, rheological and mechanical measurements show that the hydrophobic associations between the blocks of C18 or C22 units prevent water solubility and flow, while the dynamic nature of the junction zones provides homogeneity and self-healing properties together with a high degree of toughness.
Journal ArticleDOI
Biomimetic materials research: what can we really learn from nature's structural materials?
TL;DR: It is suggested that Serendipitous discovery from the observation of nature will be gradually replaced by a systematic approach involving the study of natural tissues in materials laboratories, the application of engineering principles to the further development of bio-inspired ideas and the generation of specific databases.

Reversible Unfolding of Individual Titin Immunoglobulin Domains by AFM
TL;DR: Single-molecule atomic force microscopy was used to investigate the mechanical properties of titin, the giant sarcomeric protein of striated muscle, and refolding of immunoglobulin domains was observed.

Nanostructured artificial nacre
TL;DR: It is demonstrated that both structural features of nacre and bones can be reproduced by sequential deposition of polyelectrolytes and clays, and their nanoscale nature enables elucidation of molecular processes occurring under stress.

Molecular mechanistic origin of the toughness of natural adhesives, fibres and composites

TL;DR: In this article, the authors used the atomic force microscope to stretch the organic molecules exposed on the surface of freshly cleaved nacre and found that the elongation events occur for forces of a few hundred piconewtons, which are smaller than the forces of over a nanonewton required to break the polymer backbone in the threads.

Mechanical and Chemical Unfolding of a Single Protein: A Comparison
Mariano Carrión-Vázquez,Andres F. Oberhauser,Susan B. Fowler,Piotr E. Marszalek,Sheldon E. Broedel,Jane Clarke,Julio M. Fernandez +6 more
TL;DR: The results indicate that mechanical unfolding of a single protein by AFM does indeed reflect the same event that is observed in traditional unfolding experiments, and the way is now open for the extensive use of AFM to measure folding reactions at the single-molecule level.
