Hello everyone,

We have a problem and were wondering if someone could kindly offer some
assistance.  We deposit hydrogels on silicon wafers or glass substrates.
 Then we dip the substrate in water or some other solvent to see how
much it swells up from absorbing the water.  Is there a reliable way to
measure the swelling in-situ?  If we dry it, then it defeats the
purpose.  Any help you can offer would be greatly appreciated.  Thank
you!
