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.
In a paper published in Science China Materials, a research team reports on a novel tetrapeptide, GFFY, which is capable of efficiently crossing the blood-brain barrier (BBB). The tetrapeptide is highly versatile in covalent ...
