Biogenic silica refers to silica formed by biological mineralization in living organisms, mainly found in diatoms, sponges, and other organisms. Compared with traditional chemically synthesized silica, bio silica has the advantages of natural origin, green environmental protection, and good biocompatibility, and has broad application prospects in fields such as medicine, food, and environmental protection.

Application areas:
In the pharmaceutical field, it is used as a drug carrier, tissue engineering scaffold, etc., for drug release, wound repair, etc.
Food field: As a food additive, it is used to improve the stability and taste of food.
Environmental protection field: as an adsorbent, used for sewage treatment, air purification, etc.
Future prospects:
With the increasing emphasis on green and environmentally friendly materials, bio silica, as a new type of green and environmentally friendly material, will have a broader application prospect.
