Hi,

I am a graduate student and fairly new to the area of microfabrication. I am
interested in bonding thin, cured layers of PDMS to create microchannels. I
am familiar with many of the papers that describe bonding using oxygen
plasma; however, I am curious as to the area required for adequate bonding.
Will I get adequate bonding if the channels (diameter 15-100 microns, length
1-2 cm) are separated by only 10 microns or do I need several hundred
microns? Does anyone know the minimum distance needed?  Thanks for your
help.

Sincerely,
Kristie
