Preparation and characterization of hydroxyapatite incorporated silica aerogel and its effect on normal human dermal fibroblast cells

Hydroxyapatite incorporated silica aerogel (HAESA) was synthesized via sol-gel APD technique. Silica-rich HAESA have higher cytocompatibility against human fibroblast cells. HAESA with weight ratio of hydroxyapatite/SiO2 equal to 0.5 has the highest cytocompatibility.
