 Bioactive glass nanoparticles have been developed as a promising material for soft and hard tissue repair and engineering due to their high biocompatibility and bioactivity. These particles can be produced through various methods such as chemical precipitation or soil gel processing with the goal of achieving either monodispers or dispersable nanoparticles. Additionally, these particles can be used in a variety of applications including drug delivery, injectable systems, scaffolds, implant coatings and particle dispersions.
