Mesoporous silica thin films form diverse structures with varying pore sizes and high surface area, which make them ideal for appliions including alysis, adsorption, and sensing. Silica thin films are synthesized by evaporating the solvent from a homogenous solution of soluble silica and surfactant prepared in ethanol/water, otherwise called evaporation induced self-assely (EISA).

A well-ordered mesoporous silicon dioxide calcium-doped xerogel (m-SXC) was synthesized by a sol–gel process. The in vitro bioactivity of the m-SXC was investigated by analyzing the apatite-forming ability in simulated body fluid (SBF) and MC3T3-E1 cell culture with materials, and the hemostatic activity of the m-SXC was determined by measuring the activated partial throoplastin time (APTT
