Müller(A) Appearance of the basic alginate/gelatin hydrogel cylinders, containing neither silica nor biosilica nor polyP·Ca2+-complex. (B) Hydrogel containing 10 µg/ml of silicatein. (C and D) Printed basic alginate/gelatin hydrogel containing 50 µmoles/L ortho-silicate (>si<). (E and F) Cylinders of hydrogel supplemented with 50 µmoles/L biosilica (>bs<). (G and H) Alginate/gelatin hydrogel cylinders containing 100 µmoles/L polyP·Ca2+-complex (>polyP<). (I and J) Hydrogel containing both 50 µmoles/L biosilica (>bs<) and 100 µmoles/L polyP·Ca2+-complex.
