how to make water more polar
Lin Yu

Thank you so much, guys. Sorry, I asked the wrong question.

This is what I'm doing: I prepared two samples with complementary gold
patterns on top. Then self-assembly monolayers were
formed on the gold patterns to make certain regions hydrophilic and the
other regions hydrophobic. After water is dropped on the
hydrophilic regions, one sample is placed on top of the other one. We kind
of hope self alignment can happen due to the capillary force of water. But
it didn't. So we are looking for some other liquid can do this better than
water.

Thanks,
