Biological materials, as physical systems, comprise substances produced by or derived from living organisms, characterized by hierarchical organization from molecular to macroscopic scales and emergent structure–property relationships. They include tissues, extracellular matrices, biominerals, and biopolymers such as collagen, chitin, cellulose, and elastin. Their properties arise from complex architectures combining organic and often inorganic phases, enabling functions such as load bearing, protection, adhesion, and signal transduction. Biological materials exhibit viscoelasticity, anisotropy, self-healing, and adaptive remodeling under mechanical or biochemical stimuli, making them central model systems for biomechanics, biomimetics, and the design of advanced bioinspired and biomedical materials.
It's almost time to dust off the Halloween decorations and adorn the house with all manner of spooky things, including the classic polyester spider webs. Scientists reporting in ACS Nano have made their own version of fake ...
