Bioactive glass nanoparticles (BGNs) are a type of nanomaterial composed of glass that has the ability to interact positively with biological tissues. These materials can bond to bones and other tissues, facilitating healing and regeneration. Typically, BGNs are composed of silicon dioxide (SiO2), calcium oxide (CaO), and phosphorous pentoxide (P2O5), and they are used in a variety of biomedical applications.
