(MeO)3Si-(CH2)3-(EG)~45 (SI 003)


This alkoxysilane with a poly(ethylene) glycol chain is ideal for imparting bioresistance on glass, silicon, and siloxane (especially, PDMS) substrates. Delamarche's group have shown (Langmuir, 2001, 17, 4090-4095) that PEG-ylation of glass and Si results in virtually permanent bioresistance. For PDMS where surface reconstruction effects are operative, the PEG monolayer is efficient for up to several days after modification.

Note: Different lengths of PEG oligomers are also available upon request.
