![Silica contains surface silanols, about 8 micron-mol/m2 to be precise. They are derivatized with silanization agents in the presence of an appropriate scavenger of the side product(s). The most commonly used reagent is a monochloro silane (monofunctional). Difunctional and trifunctional ligands are also affordable to be used.
