Biocrystal

A biocrystal is a natural or biologically produced crystal, often composed of minerals like calcium carbonate, silica, or other biological materials. These crystals form within living organisms or biological processes and can serve functions such as structural support, protection, or communication. Unlike synthetic crystals made in laboratories, biocrystals are formed through natural biological mechanisms, often at ambient temperatures and pressures. They are found in shells, bones, and diatoms. Understanding biocrystals helps scientists learn how organisms build hard structures efficiently and can inspire new materials in medicine, engineering, and environmental applications.
