Advances in microbial mineralization-inspired biomimetic functional materials

Abstract:

Microbial mineralization is widespread in nature， and can generate natural microbial minerals with diverse structures，different compositions，and superior performance， such as biological apatite，calcium magnesium carbonate，magnetite，silica minerals，etc. The main mechanism is divided into microbial induced mineralization and microbial controlled mineralization. In the process of microbial mineralization，the organization and metabolic functions of microorganisms play an important role，providing a theoretical basis for the preparation of biomimetic mineral materials with specific components and functions. Compared with mineral materials synthesized by traditional physical or chemical methods， biomimetic synthesis of mineralized materials by simulating the formation process of microbial mineralization not only has a highly controllable structure， but also has higher biocompatibility，which has potential applications in the field of biomedicine. However，it is still a challenge to accurately simulate the mineralization process of microorganisms. This article introduces the process of microbial mineralization and its regulatory factors，and further reviews the research progress of biomimetic synthesis of functional materials inspired by microbial mineralization in recent years.
