The present invention relates to bacterial cell membrane-adhering bioactive glass nanoparticles containing SiO 2, CaO, and AgO, having a particle size of 1 to 100 nm, and having mesoporous pores, and biocell-stimulating ions and antibacterial drugs It has the effect of protecting the hard tissue from bacteria while stimulating the stem cells to differentiate the cells of the infected hard tissue. In addition, by adjusting the size of the glass nanoparticles to a nano size, the glass nanoparticles are attached to the cell membrane of the bacteria, so that ions and antibacterial drugs can be efficiently delivered into the bacteria.
