PDMS has fairly high
permeability for a lot of fluids and oils, and will leak with time.  You will
probably need to coat with a perfluro compound as a barrier.

Subject: [mems-talk] flowing in rhodamine in pdms channel

Hi all,

I've been trying to flow in fluorescence die (Rhodamine) in a PDMS microfluidic
channel to do some flow characterizations.

The problem is, the vicinity of the pdms channel became bright as well after
about 5 minutes.

It almost seemed like that the fluoresent die was diffused into the pdms.

Is there a way to solve this problem?

Thanks!

TJ
