Our body contains numerous crystalline structures that are fundamental to the working of the organism. We stand up straight because our body has a skeleton made up of calcium phosphate crystals. We keep our balance thanks to calcite crystals that are found in the inner ear, and we chew with teeth made with apatite microcrystals. Have you ever thought about the structure of our bones? Do you know how crystallography helps to make prostheses and implants that the body won't reject? Would you like to know how toothpaste is made? |
