Silanization is the covering of a surface through self-assembly with silane-like molecules. Mica, glass and metal oxide surfaces can all be silanized, because they contain hydroxyl groups which attack and displace the alkoxy groups on the silane thus forming a covalent -Si-O-Si- bond.

[edit] Alkoxysilanes

The alkoxy groups usually used are the methoxy (-OCH₃) and the ethoxy (-OCH₂CH₃) groups.

[edit] Aminosilanes

• APTES (3-aminopropyl)-triethoxysilane
• APDEMS (3-aminopropyl)-diethoxy-methylsilane
• APMES (3-aminopropyl)-dimethyl-ethoxysilane

[edit] Glycidoxysilanes

• GPMES (3-glycidoxypropyl)-dimethyl-ethoxysilane

[edit] Mercaptosilanes

• MPTS (3-mercaptopropyl)-trimethoxysilane
• MPDMS (3-mercaptopropyl)-methyl-dimethoxysilane
