Description
Process for obtaining fluoride-doped citrate-coated amorphous calcium phosphate nanoparticles. This material has applications in biomedicine due to its biodegradability and bioactivity; it also promotes cell adhesion and osteogeneration. In dentistry, it may be used in toothpastes, mouthwashes, chewing gums, gels and fluoride varnishes as a remineralising agent of dentine and enamel. The process to generate these particles is eco-efficient and eco-friendly, as it does not leave any acid residue; it consists of a single stage and it is the first time that an amorphous calcium phosphate coated with citrate and doped with fluoride, which enhances its remineralising action, is obtained.
