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.
From claims that vaccines don't work to manipulated images and deliberately misrepresenting what politicians say, social media is often rife with misinformation. But far from being a recent phenomenon, there is nothing new ...
Researchers have developed a new class of ultra-thin, flexible bioelectronic material that can seamlessly interface with living tissues. They introduced a novel device called THIN (transformable and imperceptible hydrogel-elastomer ...
