A method for manufacturing a bioactive glass includes the steps below. A precursor and a polar solvent are mixed to form a mixed solution, in which the precursor includes a silicon precursor, a calcium precursor and a phosphorous precursor. The mixed solution is atomized to form mixture droplets. The mixture droplets are oxidized at an environment of about 500 to about 900℃ to form the bioactive glass.一種生物活性玻璃的製造方法,其包含下列步驟。混合前驅物及極性溶劑,以形成混合物溶液,此前驅物包含矽前驅物、鈣前驅物與磷前驅物。霧化此混合物溶液,以形成混合物液滴。於約500至約900℃之一環境下氧化混合物液滴,以形成生物活性玻璃。10‧‧‧機制110‧‧‧混合物液滴112‧‧‧微胞112’‧‧‧孔洞120、130‧‧‧粒子140‧‧‧介孔球形生物活性玻璃
