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.
Imagine a tiny vehicle with a nanomagnetic structure, which can be steered through the human body via external magnetic fields. Arriving at its destination, the vehicle may release a drug, or heat up cancer cells without ...

If we compare the right to the left hand, we can see these are specular images—that is, like symmetrical shapes reflected in a mirror—and they cannot superimpose on each other. This property is chirality, a feature of ...
