Mikael,

          The secret to treating surfaces to promote total
hydrophobicity is a) Totally dehydrate then treat with the vapor of the
right chemical.  We manufacture equipment designed to do this.  Knowing
from experience that the cost of the equipment is usually beyond an
academic budget we can offer free tests of the treatment.  Contact me
directly.  Bill Moffat CEO Yield Engineering Systems.  925 373 8353.

Subject: [mems-talk] PEG-coating of sealed glass or silicon channel?

Hi.

Does anyone know of a good protocol or reference for coating a sealed
glass or silicon channel with PEG (or something similar)? I'm trying to
reduce the amount of sticking of particles/cells to the surfaces and was
told that PEG might do the trick?

best regards
