Hi Kevin, The easiest method is vapor-phase SAM (self-assembled monolayer). Perfluorinated silanes can give you >110 deg contact angles on glass. Depending on your glass material you may need to use some adhesion layers (to get better surface coverage and enhance stability of coating against contacts with liquids). You may coat open microchannel or even buried channel (fully assembled device). Let me know if you have any questions or need help.

All that matters for me is contact angle (the higher the better), so other suggestions are appreciated as well. Any specific protocol details would be useful. Thanks, Kevin Paul Nichols
