The goal that mesoporous silicaxerogels containing siliver had no negative effect on cell viability could be achieved by reducing the siliver content in materials.
The silicaxerogels were synthesized by ambient pressure drying method with hydrofluoric acid (HF) as catalyzer. The influence of catalyzer and drying method on the xerogels were analyzed.
