Anwendungen & Verwendung
Verwenden
Bis(dimethylamino)-dimethyl silane has been used to silanize pH-sensitive microelectrodes, used to measure the membrane potential in oocytes, in an experimental procedure aimed towards cloning and characterizing human electrogenic Na+-cotransporter isoform (hhNBC). It is also used for microelectrode measurements, in a study conducted to measure carbon dioxide transport through membranes. It is also used in electronic film deposition.
