3-Glycidoxypropyldimethoxymethylsilane (GDMMS) is an epoxy-silane that is used to form a silane based coupling agent for functionalization of a variety of substrates. The epoxy groups allow good adhesion of surface atoms and form a stable polymeric structure. 3-Glycidoxypropyldimethoxymethylsilane (GDMMS) precursor was used to develop zwitterionic push – pull chromophore and carbazole-derivatives-doped hybrid organic–inorganic homogeneous films. GDMMS can surface modify indium tin oxide (ITO) glass substrate for the immobilization of surface atoms which can be further used for the electrochemical detection and labeling. It can also be used as a hardener in the formation of multi-component silicone based rubber. 3-Glycidoxypropyldimethoxymethylsilane (GDMMS) is an epoxy-silane that is used to form a silane based coupling agent for functionalization of a variety of substrates.
