    Application
    Hydroxyapatite Nanoparticles/Nanopowder, characterized as a white powder, serve a pivotal role in medical and dental applications due to their excellent biocompatibility and non-toxicity. These nanoparticles are based on calcium hydroxyapatite (CaHap), a naturally occurring mineral that mimics the primary component of human bone and tooth mineral. The unique crystalline structure of hydroxyapatite enables it to integrate seamlessly with bone and tooth tissues, promoting its adoption as a biomaterial for artificial teeth, bone grafts, and fillers in cements and polymers. Beyond structural and cosmetic uses, hydroxyapatite nanoparticles exhibit properties beneficial for broader applications, such as ion exchangers and adsorbents in protein chromatography. Furthermore, their capacity to replace surface ions with fluoride ions offers additional protection to teeth. Recent advancements have also leveraged their ionic conductivity for technological applications, including sensors and catalysts. This versatility highlights the significant potential of hydroxyapatite nanoparticles as a multifunctional material in both medical and technological fields.
