Formation and Mechanical Properties of Membranes Formed at the Surface of Walnut Stain Extract Solutions

Abstract : Materials based on biological molecules and produced without external energy sources may represent avenues for the design of new applications as self-healing and self-replicating compounds. Herein the synthesis of self-standing membranes from walnut stain extracts when exposed to ambient air is presented. These membranes are mechanically robust and do not entirely decompose upon heating up to 800 °C. They are composed of microorganisms (not yet identified) from the ambient air which are hold together by a dense extracellular matrix. The molecules of this extracellular matrix have been characterized by means of force extension curves performed by Atomic Force Microscopy.
