Hi Every one, I am trying to do a diffusion study of flourescent dye through mems structure. I want to make a time vs diffusion profile and see how flourescent dye enters into mems structure with passage of time. My microstructures are SU8 and are made through conventional Photolithography. I ve been trying hard to diffuse flourescent dyes into my microstructures but I havent succceeded so far. Can Any one give me some idea?? thanks in advance REGARDS Muhammad Ali Malik, PhD IFM Department, Linköping University, Sweden Tel(Office): +4613282610 Tel(Mobile): +4673-6240509
