Hi,

  I am currently working on microvalve design for drug delivery application
specifically in detecting glucose concentration. I read about the use of
hydrogel that can swells and shrinks in response to the changes in the glucose
concentration. I don't really have much knowledge in the Chemistry area. My
question is the hydrogel relatively easy to synthesize in the lab? Can the
hydrogel be purchased from a supplier? Anybody out there that are currently
working on the hydrogel?

  I would appreciate any input.

  Thank you.
