[labnetwork] PDMS mold process?

[Gerald Lopez]

Hi, Russ –

PDMS processing for soft lithography is something you want to try to keep
out of the cleanroom, or at least have a separate "dirty space" with strict
protocols to manage this type of work. Once PDMS gets on "clean" surfaces,
it's extremely difficult to remove. Happy to have a call with you and our
team to give you some pointers and answer any questions you might have.

Best,
Gerald
