Mechanics of plant fruit hooks
No full textHook-like surface structures, observed in some plant species, play an important role in the process of plant growth and seed dispersal. In this study, we developed an elastic model and further used it to investigate the mechanical behaviour of fruit hooks in four plant species, previously measured in an experimental study. Based on Euler–Bernoulli beam theory, the force–displacement relationship is derived, and its Young's modulus is obtained. The result agrees well with the experimental data. The model aids in understanding the mechanics of hooks, and could be used in the development of new bioinspired Velcro-like materials
Terminal contact elements of insect attachment devices studied by transmission X-ray microscopy
No full textFor the first time, the terminal elements (spatulae) of setal ( hairy) attachment devices of the beetle Gastrophysa viridula ( Coleoptera, Chrysomelidae) and the fly Lucilia caesar(Diptera, Calliphoridae) were studied using transmission X-ray microscopy (TXM) with a lateral resolution of about 30 nm. Since images are taken under ambient conditions, we demonstrate here that this method can be applied to study the contact behaviour of biological systems, including animal tenent setae, in a fresh state. We observed that the attached spatulae show a viscoelastic behavior increasing the contact area and providing improved adaptability to the local topography of the surface. The technique can be extended to TXM tomography, which would provide three-dimensional information and a deeper insight into the details of insect attachment structures

Localization of Phenolic Compounds at an Air-Solid Interface in Plant Seed Mucilage: A Strategy to Maximize Its Biological Function?
No full textGiven a low concentration of phenols in the naturally occurring aqueous lubricant (mucilage) from hydrated seeds, their biological functions should be severely limited. Here, we introduce an undisclosed natural strategy that enables maximization of phenolic functions through exposing the phenols at the air-seed solid interface. Our findings not only offer a new perspective on plant reproduction physiology but also provide insights into an innovative design of lubricating biomaterials with additional phenolic functions.
