Descripción general

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

Aplicación

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.

A novel sulfur/graphene nanosheet (S/GNS) composite was prepared via a simple ball milling of sulfur with commercial multi-layer graphene nanosheet, followed by a heat treatment. High-resolution transmission and scanning electronic microscopy observations showed the formation of irregularly interlaced nanosheet-like structure

Nonspecific protein adsorption, particularly fibrinogen (Fg), is thought to be an initiating step in the foreign body response (FBR) to biomaterials by promoting phagocyte attachment. In previous studies, we therefore prepared radiofrequency glow discharge (ethylene oxide)-like tetraglyme (CH(3)O(CH(2)CH(2)O)(4)CH(3)) coatings adsorbing

Physical and photolithographic techniques are commonly used to create chemical patterns for a range of technologies including cell culture studies, bioarrays and other biomedical applications. In this paper, we describe the fabrication of chemical micropatterns from commonly used plasma polymers.

Previous studies have showed that radio-frequency plasma deposited tetraglyme coatings greatly reduced fibrinogen adsorption (Gamma(Fg)) from highly diluted plasmas (0.1 and 1%) and subsequent platelet adhesion under static conditions. In this study, the protein resistant properties of tetraglyme were re-examined

Poly(ethylene) oxide (PEO) is a technologically important polymer with a wide range of applications including ion-exchange membranes, protein crystallization, and medical devices. PEO's versatility arises from its special interactions with water. Water molecules may form hydrogen-bond bridges between the ether
