The manufacture of low-cost, protein-friendly, biocompatible materials
is important for biomedical applications. A method is presented for m
aking glass surfaces-on which the globular protein shape is often lost
-benign to proteins by covalently grafting relatively short poly(ethyl
ene glycol) chains (functionalized with trimethylsilane, see Figure),
which form a brush-like self-assembled monolayer.
