Importantly, our strategy indicates that the modified attributes of FLG–TA enhance its suitability for dental biomaterials, thereby paving the way for safer and more effective dental applications. Results and Discussion Synthesis of FLG–TA results in a few-layered structure with

• Hap NRs will be highly useful in the fabrication of novel implants for orthopedic and dental applications. Materials and Methods The experiments were performed in a 1000 mL round bottom flask filled with calcium carbonate (CB powder), (NH4)2HPO4 and ammonia solution. The oil bath setup was used to

• nanoparticles on enamel is important in dental applications, as shown by AFM nanomanipulation experiments. The motion of nanoparticles on a surface can be also driven by quartz tuning forks coupled to scanning electron microscopy. As mentioned above, these techniques hold great potential for a better
