Dear Hong,
What is the channel profile you want? we can probably build you a master out of
Si or pyrex.

100micro width, 20-50 micro depth and 1cm length. We don't want to fabrication
master by ourself. Does anyone know where can we buy some? Any proper material
of master suitable for PDMS channel fabrication is fine.
