Silica an overview ScienceDirect Topics

Silica gels are well known for their adsorption properties and, hence, employed in many industrial processes. Silica gel due to its high surface area and particle size are used in catalyst formulations for applications in catalytic cracking [84, 83]. Fig. 4.6 illustrates the formation of silica sols and subsequently, the silica gels [85].

Spin column-based nucleic acid purification Wikipedia

Procedure. The stages of the method are lyse, bind, wash and elute, i.e. lysis of cells, binding of nucleic acid to silica gel membrane, washing the nucleic acid bound to the silica gel membrane and elution of the nucleic acid. To lyse, the cells of a sample are processed with a lytic procedure, which involves breaking the cell membrane and freeing the nucleic acid.
