General description
Dodecyltriethoxysilane (DTES) is an organosilane, which is used as a coupling agent. It forms alkylsiloxane based films that can be used to tune the wettability and facilitate a variety of surfaces with hydrophobicity.
Reaction between dodecene and triethoxysilane yields dodecyltriethoxysilane. 1
Application
A study reports the use of dodecyltriethoxysilane to form a silica nanofluid which alters the water contact angle of an oil-wet carbonate substrate. {68}
Dodecyltriethoxysilane can be used in the surface treatment of calcite crystals for the determination of the effect of wettability with the incorporation of nanoparticles. It may be electrodeposited with tetraethoxysilane, which can be used as an anti-corrosive coating on mild steel.

Intravital fluorescence imaging has great potential in biological and biomedical research, as it provides the ability to directly observe biological structures and processes in their natural state. Contrast agents for intravital imaging applications should exhibit good biocompatibility, multiphoton fluorescence, and
