Group,

is anyone familiar with removing excess residues or uncured monomer
from PDMS? A patterned imprint residue is highly noticable anytime PDMS
comes in contact with glass in particular. Usually this imprint can be
seen through side illumination or scattering off the glass.
        So far I've tried pulsed and unpulsed sonication of the PDMS mold in
both water and dilute ethanol, this only seems to improve things
marginally.

Thanks,

C. Khoury
