Silica-based methods — DNeasy Tissue Kits DNeasy Tissue technology provides a simple, reliable, fast, and inexpensive method for isolation of high-quality DNA. This method is based on the selective adsorption of nucleic acids to a silica-gel membrane in the presence of high concentrations of chaotropic salts (Figure 4).

Granular, vitreous, porous form of silicon dioxide
Silica gel is an amorphous and porous form of silicon dioxide (silica), consisting of an irregular tridimensional framework of alternating silicon and oxygen atoms with nanometer-scale voids and pores. The voids may contain water or some other liquids, or may be filled by gas or vacuum. In the last case, the material is properly called silica xerogel. Silica xerogel with an average pore size of 2.... Wikipedia
