PEG (polyethylene glycol) and ITO (indium tin oxide)
PEG "silane" is $\ce{HOCH2CH2O-PEG-CH2CH2CH2-Si(OCH3)3}$.  (Pt-catalyzed $\ce{HSi(OCH3)3}$ addition to the terminal allyl monoether.)  A metal oxide surface can be hydrated, (bulk)M-OH.  The TMS end hydrolyzes and dehydrates to tetrahedrally covalently bonded $\ce{HOCH2CH20-PEG-0Si(OM#bulk3)}$.  The alcohol polyethoxy end hydrated waves in the water, and the protein ignores the PEGylated surface. 

An especially fine biocompatibilizer rendering nearly any organic surface except silicone rubber invisible to protein deposition and denaturation is poly(N-vinyl pyrrolidone).  It can be linearly radiation grafted into organic surfaces (visualize with Congo Red).  Plexiglass gives a 19 degree average contact angle in saline and implants with neither cellular or humoral reaction.  NVP plasma deposition gives you sludge.  There is no obvious (inexpensive) chemical attachment of its low polymer or oligomer to a surface.  Pity.
