Allgemeine Beschreibung

Tetraethylenglycol (TEG) ist ein Oligomer aus Polyethylenglycol. Es handelt sich um eine transparente, farb- und geruchlose, hygroskopische Flüssigkeit von geringer Flüchtigkeit, die in Ethylalkohol löslich und in Wasser sehr gut löslich ist.

Anwendung

Wird für die Synthese des Monomers Tetraethylenglycol-Methacrylat verwendet.

Die TEG-Plasmaabscheidung mittels Glimmentladung macht Oberflächen beständig gegenüber Proteinadsorption und Zellbindung.

Vorsicht

Nicht verwechseln mit Glycofurol, welches auch manchmal Tetraglykol genannt wird.

Synthesis of Magnetic Nanoparticles for Biosensing

Professor Randal Lee (University of Houston, USA) discusses design considerations for iron oxide magnetic nanospheres and nanocubes used for biosensing, including synthetic procedures, size, and shape. The effects of these variables are discussed for various volumetric-based and surface-based detection schemes.

Degradable Poly(ethylene glycol) Hydrogels for 2D and 3D Cell Culture

Progress in biotechnology fields such as tissue engineering and drug delivery is accompanied by an increasing demand for diverse functional biomaterials. One class of biomaterials that has been the subject of intense research interest is hydrogels, because they closely mimic the natural environment of cells, both chemically and physically and therefore can be used as support to grow cells. This article specifically discusses poly(ethylene glycol) (PEG) hydrogels, which are good for biological applications because they do not generally elicit an immune response. PEGs offer a readily available, easy to modify polymer for widespread use in hydrogel fabrication, including 2D and 3D scaffold for tissue culture. The degradable linkages also enable a variety of applications for release of therapeutic agents.
