Two photon polymerization on glass substrate

I am trying to make polyethylene glycol diacrylate (PEGDA) micro pattern on glass substrate, but find it hard to keep the pattern on the surface of the glass after cleaning the residue with DI water. Is there a way to increase the adhesive of the polymer pattern on the glass surface?

I read the website for 3Dresyns - it seems they have products for Two Photon Polymerisation - I wonder if you can use that with Formlabs?
