General description

Tetraethylene glycol dimethyl ether or tetraglyme is an organic aprotic colourless solvent with film forming ability.

Application

Tetraglyme coating was applied on glucose sensors, such as Nafion™ by RF to render it “non fouling” and enhancing linking of bio mimetic molecules to the surface. Tetraglyme helps in selective adsorption of proteins while promoting cell adhesion. Other general uses include as an electrolyte in lithium ion battery.
