Hydroxyapatite (HAp), with the chemical formula Ca10(PO4)6(OH)2, is a ceramic biomaterial whose chemical structure and physical properties closely resemble those of bone tissue . Due to its properties, such as bioactivity, osteoconductivity, and osteoinductivity, it is widely used in bone tissue engineering applications, particularly in orthopaedics and dentistry. In addition, HAp is used as an additive to polymers, either as a coating or as a filler, significantly increasing the attractiveness of polymer-based materials for biomedical applications. Numerous studies show that the incorporation of HAp can improve the biocompatibility of base materials, regulate the degradation rate, which is important in the case of bioactivity, and that the material itself can form strong chemical bonds between the implant and the patient's tissues .
