Biominerals are mineral materials produced by living organisms. These inorganic substances are formed through a biological process called biomineralization. The composition and structure of biominerals are controlled by the organism, leading to a wide variety of forms and functions. Common elements found in biominerals include calcium, phosphorus, silicon, and iron.

The most prevalent biominerals are based on calcium carbonate and calcium phosphate. Calcium carbonate biominerals, such as aragonite and calcite, are found in shells of mollusks, coral skeletons, and the exoskeletons of crustaceans. Calcium phosphate biominerals, primarily hydroxyapatite, are the main component of vertebrate bones and teeth, providing structural support and protection.

Silicon-based biominerals, known as phytoliths, are produced by plants and play a role in defense and structural integrity. Iron biominerals are utilized by some bacteria for energy storage or detoxification.

The formation of biominerals often involves organic matrices secreted by the organism, which act as templates and influence the crystal growth and morphology of the mineral phase. This controlled process allows for the creation of materials with remarkable mechanical properties, such as high strength and toughness, often exceeding those of synthetic counterparts.

Biominerals serve diverse biological functions, including structural support, defense against predators, sensory perception, ion storage, and waste sequestration. Studying biominerals provides insights into the evolution of life, the interaction between biology and geology, and can inspire the development of new advanced materials.
