Hierarchical bioglass scaffolds: Introducing the "milky way" for templated bioceramics [PDF]

open access: yes, 2015
Free standing hierarchical bioglass scaffolds were prepared by the ISISA (ice-segregation-induced self-assembly) method. Commercial low-cost precursors such as Ludox® HS-40 and cow milk were employed as the source of SiO2 and biominerals (Ca(ii), P(v ...
