Abstract

The present invention provides a method of preparing a bioactive glass scaffold, said method comprising the steps of: (i) preparing a slurry comprising bioactive glass powder and a binder; (ii) contacting a polymer template with said slurry so as to form a coated polymer template; (iii) allowing the coated polymer template obtained in step (ii) to dry at ambient temperature; (iv) forming a bioactive glass scaffold by heat treating the coated polymer template obtained in step (iii) to remove the polymer template; and (v) sintering the bioactive glass scaffold obtained in step (iv).
