Cationic silica sol has a wide range of application prospects in the fields of separation and purification of molecules, catalytic reactions, biomedicine, etc. due to its unique physical and chemical properties.
Separation and purification of molecules
Cationic silica sol has good adsorption properties due to its high surface area and microporous structure, and can be used to separate and purify molecules. For example, in the field of biomedicine, cationic silica sol can be used for protein separation and purification. By adjusting its surface charge density and pore size, it can selectively adsorb target proteins to achieve efficient separation and purification.
